Calculate the number of moles of 70.0 g of NaOH. Molar mass of NaOH is 40.0 g/mol
Question
Calculate the number of moles of 70.0 g of NaOH. Molar mass of NaOH is 40.0 g/mol
Solution
To calculate the number of moles, you can use the formula:
Number of moles = mass / molar mass
Given: Mass of NaOH = 70.0 g Molar mass of NaOH = 40.0 g/mol
Substitute the given values into the formula:
Number of moles = 70.0 g / 40.0 g/mol = 1.75 moles
So, there are 1.75 moles of NaOH in a 70.0 g sample.
