If an aqueous solution is 1.54 % by weight in sodium chloride and contains 6.96 g of sodium chloride, what mass of water is present in the solution?

• chemistry -

If a solution is 1.54% w/w then for 100 g of solution 1.54 g of the soluton is NaCl and the other 98.46 g is water.

If we have 2 x 1.54 g of NaCl we must have 2 x 98.46 g of water.

So if we have 6.96 g of NaCl how much water?

• chemistry -

200g
