Question

[b] Calculate the concentration of a solution which contains 2.5g of salt dissolved
in 50g of water.
is shown in the following velocity-graph. Study the graph​

Answer 1

ANSWER

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%.
