Answer:

200grams

Explanation:

The balanced chemical equation for this reaction is given as follows:

H2(g)+F2(g) → 2HF(g)

This equation shows that it takes 1 mol of both hydrogen gas (H2) and fluorine gas (F2) to produce 2 moles of hydrogen fluoride (HF)

Hence, 5 moles of fluorine gas (F2) will produce 5 × 2 = 10 moles of HF.

In order to convert the mole value of HF to gram value, we use the following formula;

Mole = mass/molar mass

Molar mass of HF = 1 + 19 = 20g/mol

mass = mole × molar mass

mass = 10 × 20

mass = 200grams of HF.
