Question

How many grams of NaOH are there in 700.0 mL of a 0.18 M NaOH solution? *

Answer 1

Answer:

E. 5.049

Explanation:

Multiply the concentration by volume (in liters) first to get moles of NaOH. Then multiply by the molar mass of NaOH to convert to grams.

0.18 M • 0.7000 L = 0.126 mol NaOH

0.126 mol • 39.997 g/mol = 5.040 g --> The closest answer seems to be e. 5.049 g
