Question

What the concentration

Answer 1

0.070 μmol/L

Step-by-step explanation:

(Step 1)

Convert milliliters (mL) to liters (L).

1,000 mL = 1 L

300. mL 1 L
----------------- x ------------------- = 0.300 L
1,000 mL

(Step 2)

Calculate the molarity.

Molarity = μmol / liters

Molarity = 0.021 μmol / 0.300 L

Molarity = 0.070 μmol
