Answer:
a) 11.55 moles of carbon dioxide gas are formed from 3.85 mole of propane.
15.4 moles of water are formed from 3.85 mole of propane.
b)0.5176 moles of water are formed from 0.647 mole of oxygen gas.
0.1294 moles of propane are consumed.
Explanation:
a) Moles of propane = 3.85 moles
According to reaction, 1 mole of propane gives 3 moles of carbon dioxide gas.
Then 3.85 moles of propane will give:
of carbon dioxide gas.
11.55 moles of carbon dioxide gas are formed from 3.85 mole of propane.
According to reaction, 1 mole of propane gives 4 moles of water gas.
Then 3.85 moles of propane will give:
of water .
15.4 moles of water are formed from 3.85 mole of propane.
b) Moles of oxygen gas = 0.647 moles
According to reaction, 5 mole of oxygen gas gives 4 moles of water.
Then 0.647 moles of oxygen will give:
of water.
0.5176 moles of water are formed from 0.647 mole of oxygen gas.
According to reaction, 5 mole of oxygen gas reacts with 1 mole of propane.
Then 0.647 moles of oxygen will give:
of propane.
0.1294 moles of propane are consumed.
The question is incomplete, here is the complete question:
A chemist measures the amount of bromine liquid produced during an experiment. She finds that 766.g of bromine liquid is produced. Calculate the number of moles of bromine liquid produced. Round your answer to 3 significant digits.
<u>Answer:</u> The amount of liquid bromine produced is 4.79 moles.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
We are given:
Given mass of liquid bromine = 766. g
Molar mass of liquid bromine, = 159.8 g/mol
Putting values in above equation, we get:
Hence, the amount of liquid bromine produced is 4.79 moles.
