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
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
