Answer:
0.057 M
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
