Question

How many grams of solid sodium hydroxide are required to make 500.00 mL of a 0.07 M NaOH solution?

Answer with two decimal places.

Answer 1

Answer #1

concentration = 0.07 M

volume = 500 ml = 0.5 L

no of moles = concentration * volume

= 0.07 M * 0.5 L

= 0.035 mol

now mass = molar mass * no of moles

grams of solid sodium hydroxide are required = 0.035 mol * 40 g/mol

= 1.4 g
