Question

A 164,5 g mixture contain xg of Na2CO3 and y g of Naci. % of Na (by
mass) is 41.945% in the mixture. Consider the following statements
(a) If y g of NaCl is dissolved in water and volume of solution become 1
L. the molarity of this solution is 1 M (approx).
(b) if y g of NaCl is present in 360 g of water, then mole fraction of Naci
in solution is 0.048 (approx).
(c) A mixture is prepared by adding xg Na,C09. y g NaCl and water. The
molarity of Na' is 3 (approx), if volume of solution is 1 L
The correct statement(s) is (are)​

Answer 1

Explanation:

A 164.5 g mixture contain xg of Na coz and y g of NaCl. % of Na (by

mass) is 41.945% in the mixture. Consider the following statements.

(a) If y g of NaCl is dissolved in water and volume of solution become

1 L, the molarity of this solution is 1 M (approx).

(b) if y g of NaCl is present in 360 g of water, then mole fraction of

NaCl in solution is 0.048 (approx).

(c) A mixture is prepared by adding x g Na coz y g NaCl and water

The molarity of Na' is 3 (approx), if volume of solution is 1L

The correct statement(s) is (are):
