Question

How many moles are in 558 grams of Hydrofluoric acid? please show dimensional analysis

Answer 1

29.4mol

Step-by-step explanation:

Using mole = mass ÷ molar mass

Molar mass of HF (hydrogen fluoride) = 1 + 19 = 20g/lol

Using the formula;

Mole = mass/molar mass

Mole = 588/20

Mole = 29.4mol
