Calculating Molarity of Solution Containing Glucose


Step 1: Calculate the number of moles of glucose

To calculate the number of moles of glucose, we need to use the formula:
moles = mass/molar mass

Mass of glucose = 3 g
Molar mass of glucose = 180 g/mol

moles = 3/180
moles = 0.01667 mol

Step 2: Calculate the volume of the solution in liters

To calculate the volume of the solution, we need to use the formula:
Volume = Mass/Density

Mass of water = 30 g
Density of water = 1 g/mL

Volume = 30/1
Volume = 30 mL

As we need the volume in liters, we will convert 30 mL to liters by dividing it by 1000:
Volume = 30/1000
Volume = 0.03 L

Step 3: Calculate the molarity of the solution

The formula to calculate molarity is:
Molarity = moles/volume

moles = 0.01667 mol
Volume = 0.03 L

Molarity = 0.01667/0.03
Molarity = 0.5556 M

Therefore, the molarity of the solution containing 3g glucose dissolved in 30 g of water is 0.5556 M.

Calculate the molarity of solution containing 3g glucose dissolved in ...
Molarity = given mass of compound /{molar mass of compound ×wt of solvent in kg}
=3/{180gm/mole × 0.03kg}
=0.55m
