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.
