Question

2C4H10+1302 -> 8CO2 + 10H₂O
If 2.46 g of H₂O are produced by a reaction, how many moles of H₂O are produced?

Answer 1

Answer:

.137 moles

Explanation:

need to know the molar mass of water which is 18.01528 g/mol

2.46 g of H₂O divided 18.01528 g/mol molar mass H₂O = moles of H₂O

2.46 divided by 18.01528 =

.137 moles

C4H10 is butane

butane is commonly used in cigarette lighters

2C4H10+1302 -> 8CO2 + 10H₂O is the burning of butane

burning butane with oxygen makes carbon dioxide and water
