What are the units of “b” in van der Waals equation?a)L/mo...

The ideal gas equation is given as (P – an²/V²)(V – nb) = nRT. So by considering the equation, we can understand that the units of the volume are equal to the units of a number of moles X be so the units of b. So b’s units = volume / number of moles so it is L/mol.

She put up her spectacles and(5) pushed her chair back from the table.“I feel so astonished,” she began, “I hardly knowwhat to say to you, Miss Eyre. I have surely not beendreaming, have I?

It danced onthe glossy hair and bright eyes of two girls, who sattogether hemming ruffles for a white muslin dress. The(5) half-finished skirt of the dress lay on the bed, and aseach crisp ruffle was completed, the girls added it to thesnowy heap, which looked like a drift of transparentclouds or a pile of foamy white of egg beaten stiffenough to stand alone.(10) These girls were Clover and Elsie Carr, and itwas Clover’s first evening dress for which they werehemming ruffles. It was nearly two years since a certainvisit made by Johnnie to Inches Mills and more thanthree since Clover and Katy had returned home from(15) the boarding school at Hillsover.Clover was now eighteen. She was a very smallClover still, but it would have been hard to find any-where a prettier little maiden than she had grown tobe. Her skin was so exquisitely fair that her arms and(20) wrists and shoulders, which were round and dimpledlike an infant’s, seemed cut out of daisies or whiterose leaves. Her thick, brown hair waved and coiledgracefully about her head. Her smile was peculiarlysweet, and the eyes, always Clover’s chief beauty,(25) had still that pathetic look which made them quiteirresistible to anyone with a tender or sympatheticheart.Elsie, who adored Clover, considered her as beau-tiful as girls in books, and was proud to be permitted(30) to hem ruffles for the dress in which she was to burstupon the world. Though, as for that, not much “burst-ing” was possible in the village of Burnet, where teaparties of a middle-aged description, and now andthen a mild little dance, rep-resented “gaiety” and(35) “society.” Girls “came out” very much as the suncomes out in the morning—by slow degrees and grad-ual approaches, with no particular one moment whichcould be fixed upon as having been the climax of thejoyful event.(40) “There,” said Elsie, adding another ruffle to thepile on the bed, “there’s the fifth done. It’s going to beever so pretty, I think. I’m glad you had it all white;it’s a great deal nicer.”“Cecy wanted me to have a blue bodice and sash,”(45) said Clover, “but I wouldn’t. Then she tried to persuademe to get a long spray of pink roses for the skirt.”“I’m so glad you didn’t! Cecy was always crazyabout pink roses. I only wonder she didn’t wear themwhen she was married!”(50) Yes, the excellent Cecy, who at thirteen hadannounced her intention to devote her whole life toteaching Sunday School, visiting the poor, and settinga good example to her more worldly contemporaries,had actually forgotten these fine resolutions, and before(55) she was twenty had become the wife of Sylvester Slack,a young lawyer in a neighboring town! Cecy’s weddingand wedding clothes, and Cecy’s house furnishing, hadbeen the great excitement of the preceding year inBurnet; and a fresh excitement had come since in the(60) shape of Cecy’s baby, now about two months old, andnamed ‘Katherine Clover,’ after her two friends. Thismade it natural that Cecy and her affairs should still beof interest in the Carr household, and Johnnie, at thetime we write of, was paying her a week’s visit.(65) “She was rather wedded to them,” went on Clover,pursuing the subject of the pink roses. “She was almostvexed when I wouldn’t buy the spray. But it cost lots,and I didn’t want it at all, so I stood firm. Besides,I always said that my first party dress should be plain(70) white. Girls in novels always wear white to their firstballs and fresh flowers are a great deal prettier, anyway,than the artificial ones. Katy says she’ll give me someviolets to wear.”“Oh, will she? That will be lovely!” cried the ador-(75) ing Elsie. “Violets look just like you, somehow. Oh,Clover, what sort of a dress do you think I shall havewhen I grow up and go to parties and things? Won’t itbe awfully interesting when you and I go out to chooseit?” Clover’s smile beamed.Q.When Clover says “She was rather wedded to them,” (line 65) she is expressing her belief that
