Question

10g glucose is dissolved in 400g of solution. Calculate percentage concentration of the solution​

Answer 1

Explanation:

concentration of a solution=

mass of soute/mass of solution* 100

10 g/400 g * 100 = 2.5 percent

Answer 2

Given :-

10g glucose is dissolved in 400g of solution.

To Find :-

The concentration of the given .

Solution :-

Mass of solute = m = 10 g

Mass of Solution = 400 g

Mass of solvent = Mass of solution - Mass of solute

=> 400 - 10 = 390 g

Therefore , By mass by mass concentration ,

Concentration of the solution is :-

$\frac{10}{400 } \times 100$

$\frac{10}{4}$

2.5 %

Henceforth , The required answer is 2.5%
