Question

if a 250ml of solutions is prepared bye by adding 50 ml of sulphuric acid in water calculate the the concentration in volume by volume percentage​

Answer 1

Answer:

Molarity, M= no. of moles/Volume(L)

Volume, V=250mL=0.25L

No. of moles, n= mass/molar mass

Mass = 49 g

Molar mass of H²SO⁴ = 98 g

n=49/98=0.5

M=0.5/0.250=2M

Hence,2M is the correct answer!!
