Question

How many moles of water are used in the production of 1.80 moles of sulfur dioxide?     SF₄   +   2 H₂O   →   SO₂   +   4 HF          

Multiple Choice

• 1.08 mol

• 1.80 mol

• 0.450 mol

• 3.60 mol

• 0.900 mol

Answer 1

Reaction: SF₄   +   2 H₂O   →   SO₂   +   4 HF       

The reaction is balanced already so we can proceed.

Now looking at the stoichiometry of the reaction, or coefficients of reactants and products, we can tell that:

To produce 1 mole of  sulfur dioxide (SO₂), we required 2 moles of water.

So to produce 1.80 moles of sulfur dioxide(SO₂), we will need 21.80 moles = 3.60 moles of water

Answer: 3.60 moles of water
