Question

A solution is prepared by dissolving 4.9g of H2So4 in 250ml of solution calculate molarity?​

Answer 1

Explanation:

molarity=no.of moles of solute per litre of solution

molar mass of h2so4 is 98

98=1 mol

4.9=x

x=4.9/98. =0.05

litre of solution =250/1000

molarity =0.05÷0.25

=0.2

hope it's clear!!!
