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.
