Question

If 250 mL of a solution contains 24.5 g H2SO4 the molarity is o 1 0.25 2. 0.35​

Answer 1

Answer:

Correct option is A)

Molarity, M=

volume(L)

no. of moles

Volume, V=250mL=0.25L

No. of moles, n= mass/molar mass

Mass = 49 g

Molar mass of H

2

SO

4

= 98 g

n=49/98=0.5

M=0.5/0.250=2M

Hence, option A is correct.
