Answer 1

A container holds 1.704 lb of HNO3 / lbof H2O and has a specific gravity is 1.38 to at 20 degree Celsius find the molarity of solution .

Solution :

Moles of HNO3:

1704 g HNO3 × (1molHNO3)/(63.01g) = 27.04 moles

Liters of solution:

2,704 kg ×( 1L)/ (1.382kg) = 1.96 L of solution

Molarity:

(27.04mol)/(1.96L) = 13.8 M

____________________________

So the molarity of the solution is : 13.8 M
