Question

a solution contain 10g of solute in 100g of solvent . its concentration in terms of mass percentage is
​

Answer 1

ANSWER IS:

Total weight of the solution= 10+100=110g

Solute mass= 10g

Its concentration=

$\frac{10}{110} \times 100$

Which is equal to 9.09%

Answer 2

Answer:

mass% of solute =9.99%

mass %of solvent =90.90%

Step-by-step explanation:

mass of solute=10g

mass of solvent =100g

mass of solution =mass of solute +mass of solvent

= 10g+100g=110g

mass %of solute =mass of solute ÷mass of solution ×100

=10 ÷110 ×100 = 9.99%

mass % of solvent =mass of solvent ÷mass of solution ×100

=100÷110 ×100=90.90%
