Question

Calculate the number of moles of sodium hydroxide in 8g of sodium hydroxide (NaOH). Na=23 O=16 H=1

Answer 1

Answer:

0.2 mol

Explanation:

Use the given values to find the molar mass.  The molar mass is 40 g/mol.

23 + 16 + 1 = 40

Using the molar mass, convert grams to moles.

(8 g)/(40 g/mol) = 0.2 mol

You have 0.2 mol of sodium hydroxide.
