Answer:

a) 0.125 M

b) 0.04888 M

c) 0.2056 M

d)  0.005625 M

Explanation:

(a) Given:

V₁ = 1.00 L

M₁ = 0.250-M

V₂ = 2.00 L

Now,

We know,

M₁V₁ = M₂V₂

where, M₂ is the molarity of the final solution

Thus,

0.250 × 1.00 = M₂ × 2.00

or

M₂ = 0.125 M

b) Given:

V₁ = 0.5000 L

M₁ = 0.1222-M

V₂ = 1.250 L

Now,

We know,

M₁V₁ = M₂V₂

Thus,

0.1222 × 0.5000 = M₂ × 1.250

or

M₂ = 0.04888 M

c) Given:

V₁ = 2.35 L

M₁ = 0.350 M

V₂ = 4.00 L

Now,

We know,

M₁V₁ = M₂V₂

Thus,

0.350 × 2.35 = M₂ × 4.00

or

M₂ = 0.2056 M

d) Given:

V₁ = 22.50 L

M₁ = 0.025 M

V₂ = 100.0 L

Now,

We know,

M₁V₁ = M₂V₂

Thus,

0.025 × 22.50 = M₂ × 100.0

or

M₂ = 0.005625 M
