The molarity of ethanol in the solution is 0.217 M
<h3>Further explanation</h3>Given
1% by mass
density = 0.996 g/ml
Required
The molarity
Solution
mass/ml of Ethanol :
1% x 0.996 g/ml = 0.00996 g/ml
For 1 L solution :
0.00996 g/ml x 1000 ml/L = 9.96 g/L
Convert to mol/L(MW ethanol=46 g/mol) :
9.96 g/L : 46 g/mol= 0.217 mol/L = 0.217 M
Or you can use equation :
