Question

How many grams of NaOH are dissolved in 3.0 liters of a 2.0 molar
solution? (The molar mass of NaOH = 40.00 g/mol)
O 80 grams
O 240 grams
O 120 grams
O 40 grams

Answer 1

Answer:

240 g

Explanation:

Molarity = (moles of solute)/(liters of solvent)

2.0 M = (moles of solute)/(3.0 L) = 6 mol NaOH

Convert moles to grams, 240 g.
