Question

A 164.5 g mixture contain x g of Na2CO3
and y g of NaCl. % of Na (by mass) is
41.945% in the mixture. Consider the
following statements.
(a) Ify 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
Na2CO3, y g NaCl and water. The molarity
of Nat is 3 (approx), if volume of solution
is 1 L.
The correct statement(s) is (are):​
