Answer 1

Answer:

ook

Explanation:

Correct option is C)

Solution:- (C) 5%

Given that:-

Mass of solute =2.5g

Volume of solution =50mL

As we know that, mass by volume percentage of the solution is given by-

Mass by volume %=

Volume of solution

mass of solute

​

×100=

50

2.5

​

×100=5%

Hence the required answer is (C)5%.
