Question

what do you mean by 10% aqueous solution of sodium carbonate

Answer 1

in 100 grams of H20(water)Now weight of H2O is 100-10=90gramsAnaqueous solutionis asolutionin which thesolventis water

Answer 2

Answer:

This means that in 100 g of solution there is 10 grams of sodium carbonate.

Explanation:

10% aqueous solution of sodium carbonate means that in 100 g of solution the mass of sodium carbonate in 10 g and remaining mass is of the water that is 90 g.

$10\%=\frac{\text{Mass of the }Na_2CO_3}{\text{Mass of the solution}}\times 100$

Mass of the $Na_2CO_3$ = 10 g
