Question

The amount (in g) of H,so, present in 250 mL of
1 M solution is
(1) 12
(2) 24.5
(3) 49
(4) 98


plz provide me solution​

Answer 1

Answer:

2) 24.5 g

Explanation:

Given,

Molarity = 1M

Mass(W) = ?

Volume = 250 ml

Molecular weight of H2SO4 = 2(1) + 32 + 16(4)

= 98 g/mol

We know that,

Molarity = W / Molecular weight × 1000 / V in ml

=> 1 = W/98 × 1000/250

=> 1 = W/98 × 4

=> W = 98 × 1 / 4

=> W = 98/4

=> W = 24.5 g
