Answer :
The total mass of water in this reaction is 72.1 grams.
What is a chemical reaction?
A chemical reaction is a process in which two, or more substances react or interact. This interaction leads to products or new substances. The reaction described can be represented as:
- C3H8 +O2 =CO2 + H2O
This is because propane reacts with oxygen and it forms carbon dioxide and water.
How to calculate the mass of a product?
In general, the mass of products is equal to the mass of reactants. This occurs due to the law of conservation that states mass is always preserved even though its form may change.
Now, let's use the information we know to calculate the mass of water.
- 44.1 g of C3H8 + 160 g of O2 = 132 g of CO2 + x g of H20
- 204.1 g of reactans = 132 g of CO2 + H2o
- 204.1 - 132 = 72.1 grams of water
