555.0 g of KNOwas used to create a 2.7M solution. What is the volume of the solution?

Solution volume is 2.03 litres.

Explanation:

First number of moles of KNO3 present in 555.0 gm will be calculated.

n = mass of the substance / mass of one mole of the substance.

n = 555 / 101.1032 (molecular weight of KNO3 is 101.103)

= 5.4 moles

Now volume can be calculated by the formula:

M = n/V (M is the molarity, n is number of moles, V is the volume.)

= n/M

= 5.4/2.7

V = 2.03 liters.

Molarity is defined as the number of moles of a substance dissolved in 1 litre of solution.
