Answer:
2.67 M
Explanation:
Molarity, which is the molar concentration of a substance, can be calculated using the formula;
M = n/V
Where;
M = molarity (M)
n = number of moles (mol)
V = volume (Litres)
Based on the provided information in this question, mass of lithium sulfate (Li2SO4) = 734g, volume = 2.5L
Using mole = mass/molar mass
Molar mass of Li2SO4 = 7(2) + 32 + 16(4)
= 14 + 32 + 64
= 110g/mol
Mole = 734/110
Mole (n) = 6.67moles
Molarity = n/V
Molarity = 6.67/2.5
Molarity = 2.668
Molarity of Li2SO4 in the solution is 2.67 M
