Question

60 ml of a 1.0 m solution of h2so4 is mixed with distilled water to make 1 l of solution. what is the molarity

Answer 1

0.057 M

Step-by-step explanation:

To find the new molarity, you need to (1) find the moles (via the molarity equation using the old molarity and volume) and then (2) calculate the new molarity (via the molarity equation using the combined volume and old moles).

(Step 1)

60 mL / 1,000 = 0.06 L

Molarity (M) = moles / volume (L)

1.0 M = moles / 0.06 L

(1.0 M) x (0.06 L) = moles

0.06 = moles

(Step 2)

0.06 L + 1 L = 1.06 L

Molarity (M) = moles / volume (L)

Molarity = 0.06 moles / 1.06 L

Molarity = 0.057 M
