Sodium hydroxide (NaOH) has a molar mass of 40.0 g/mol. What is the mass of 0.200 mol of sodium hydroxide?
Question
Sodium hydroxide (NaOH) has a molar mass of 40.0 g/mol. What is the mass of 0.200 mol of sodium hydroxide?
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.
