Sodium hydroxide (NaOH) has a molar mass of 40.0 g/mol. What is the mass of 0.200 mol of sodium hydroxide?
Question
What is the mass of 0.200 mol of sodium hydroxide?
Sodium hydroxide (NaOH) has a molar mass of 40.0 g/mol.
Solution
To find the mass of the sodium hydroxide, you need to multiply the given amount of moles by the molar mass of sodium hydroxide.
Given: Molar mass of NaOH = 40.0 g/mol Amount of NaOH = 0.200 mol
Using the formula: Mass = Molar mass x Amount of substance
Substitute the given values into the formula:
Mass = 40.0 g/mol x 0.200 mol = 8.0 g
So, the mass of 0.200 mol of sodium hydroxide is 8.0 g.
