Question

A solution contains 40g of common salt in 320g of water. calculate the concentration in terms of mass by mass percentage of the solution​

Answer 1

Answer:

0.11

Explanation:

Mass by mass percent of solution

= mass of solute ÷ mass of solution

=40/320+40

=40/360

=0.11 is your answer

➦Given : -

Mass of Solvent(water) = 320g

Mass of Solute(salt) = 40g

➦To Find : -

The concentration in the terms of mass by mass percentage of the solution ..

➦Formula Used : -

↠Mass of Solution = Mass of Solute + Mass of Solvent ..

➦On Substituting Values : -

➣ACCORDING TO THE FORMULA

⇒40g + 320g

⇒360g [Answer]

➦Mass Percentage of Solution : -

↠Mass of Solute/Mass of Solution × 100

⇒40/60 × 100

⇒11.1% [Answer]
