Question

5 moles of glucose are dissolved in 1.1kg of water. If density of solution is 1.25g/ml,then determine %w/v of glucose?

Answer 1

Explanation:

pls mark as brainlist answer

Answer 2

Answer:

First we will calculate molar mass of glucose, which is 180

now we will calculate mass of glucose in 5 mol

mass = 5× 180 = 900g

weight of solution = weight of solute + weight of solvent

W = 900 + 1.1 × 1000 = 2000 g

volume of solution = 2000÷ 1.25 = 1600ml

%w/V = 900/1600×100 = 56.2 %...
