Question
Q127) Concentrated aqueous sulphuric acid is 98% H_{2}SO_{4}(w/v) and has a density of 1.80 gmL^{–1}. Molarity of solution

SOLUTION

Given 98%H_{2}SO_{4}(w/v)

Thus 100 ml ofH_{2}SO_{4} have 98 g of H_{2}SO_{4} or 1 mole of H_{2}SO_{4}

Now 100 mL have 1 mole

1L = 10 moles

Therefore answer is 10M

Answer : (c)
