Question

Given the following equation:

2F2+ 2H2O = 4HF+ O2
What mass of fluorine is needed to completely react with 3.6 grams of water?

Molar mass of F2 = 38.00 g/mol
Molar mass of H2O= 18.02 g/mol

Answer 1

Answer: 7.6g of Fluorine

Step-by-step explanation:

Looking at the equation for the reaction.

2F2+ 2H2O = 4HF+ O2

Which means;

36.04g of Water (H2O) reacts with 76g of Fluorine (F)

1g of H2O would react with 76g/ 36.04g of F

3.6 g of water is needed to react with ; (76/ 36.04 x 3.6) = 7.59 approx 7.6g of Fluorine .
