Question

find the molarity of a solution of H2 S o4 having 4.9 gram of it dissolved in 500 cm cube of solution​

Answer 1

500 cc = 0.5 L

molar mass of h2so4= 2+32+64=98g

molarity=no of moles/molar mass*volume

= 4.9/98*0.5

=4.9/49

= 0.1molar

Answer 2

Answer:

Explanation:

Mass of solute = 4.9 gm

molar mass of solute= 98gm

Volume of solution = 0.5 litres

Molarity= 4.9×1000/98×0.5

=100 molar
