Answer:
120g
Explanation:
Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.
Thus, we need to convert mass of water to moles using its molar mass:
Moles H2O (Molar mass: 18g/mol):
63g H2O * (1mol / 18g) = 3.5 moles H2O
Converting to moles of CO2:
3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2
Mass CO2 (Molar mass: 44g/mol):
2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

Answer:
8.2 x 106^-11
Explanation:
To begin this problem you must remember the basic rule of scientific notation, which is, must be between 1-10. .000000000082 is much smaller than 1. However by moving the decimal 11 spots to the right, we can make it 8.2
Continue to move the decimal to the right until the value is in the 1-10 range. Make sure to count the moves to the right.
Once the decimal is in the right spot count the spots moved.
Since the number is wayyy smaller than the answer given the number will be negative 10^-11, in order to make it what is was before.
