The answer is 0.001 Molessolution; given data: volume of soln=250 ml mass of caco3=2.5gram molar mass of caco3=100 moles=mass/molar mass moles=2.5/100 moles=0.025 moles... therefore; molarity of soln=no.of.moles÷vol of soln in litres. (250ml----->0.25litres) molarity=0.025÷0.25 molarity=0.1moles now, 10 ml of caco3 solution dilute in to 1 litre solution so; M1×V1=M2×V2. ( therefore; V1=10ml--->0.01 litre V2=1L ; M1=0.1 moles and M2=?..)0.1×0.01=M2×1M2=0.001 moles.... and so; the concentration of resultant solution is 0.001 moles....hope u clear...!👍👍😊

Calculation of Concentration of Resultant Solution


Given Data


  • Volume of CaCO3 solution = 250ml

  • Mass of CaCO3 in solution = 2.5grams

  • Volume of diluted solution = 1 litre

  • Volume of solution taken for dilution = 10ml



Calculation

To calculate the concentration of the resultant solution, we need to first calculate the concentration of the original solution.

The concentration of the original solution can be calculated using the formula:
Concentration = (mass of solute/volume of solution) x 1000

Substituting the given values, we get:
Concentration of original solution = (2.5/250) x 1000 = 10g/L

Now, we can use the formula for dilution to calculate the concentration of the resultant solution.
The formula for dilution is:
Concentration of resultant solution = (Concentration of original solution x Volume of original solution)/(Volume of original solution + Volume of diluent)

Substituting the given values, we get:
Concentration of resultant solution = (10 x 10)/(10 + 1000) = 0.099g/L

Answer

The concentration of the resultant solution is 0.099g/L.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Reactions can occur at different speeds.Reason: Rate of reaction is also called speed of reaction.
