Question

A solution is prepare by adding of 2g of a solution A and 18g of water calculate the mass percent of the solution

Answer 1

Mass percent will be solute divided by solution into 100 which is
2÷20*100

Answer 2

ANSWER
>>>>>>>>>>>>>>>>>>>>>>>>>>>

MASS OF WATER -------- 18 g
MASS OF A -------- 2 g

TOTAL MASS OF SOLUTION
= 18+2
= 20 g
------------------------------------------
MASS PERCENT =
MASS OF SOLVENT / MASS OF SOLUTION × 100
--------------------------------------------

MASS PERCENT OF WATER = 18/20 × 100
= 18×5
= 90%

MASS PERCENT OF A = 2/20 × 100
= 10%

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

MASS % OF WATER= 90%
MASS % OF A = 10%
