Under standard temperature and pressure conditions, it is known that 1 mole of a gas occupies 22.4 liters.
From the periodic table:
molar mass of oxygen = 16 gm
molar mass of hydrogen = 1 gm
Thus, the molar mass of water vapor = 2(1) + 16 = 18 gm
18 gm of water occupies 22.4 liters, therefore:
volume occupied by 32.7 gm = (32.7 x 22.4) / 18 = 40.6933 liters
Answer:
0.13 cm^3
Explanation:
Volume = Mass/ density
1.8 g/ml / 14g = 0.128571429
Both numbers have 2 significant digits.
With that, the answer rounds to 0.13
The final answer is 0.13 cm(don't forget the units for volume)

The percent by mass of oxygen in carbon dioxide (
) is 72.71%.
<u>Scientific data:</u>
- Molar mass of oxygen gas = 32 g/mol.
- Molar mass of carbon = 12 g/mol.
To calculate the percent by mass of oxygen in carbon dioxide ():
First of all, we would calculate the molar mass of carbon dioxide ();
For the percent by mass of oxygen:
Substituting the parameters into the formula, we have;
Percent mass of oxygen = 72.71%

Answer:
Explanation:
The difference is in the amount of heat required to increase their temperature by 1 °C
It takes 4.19 joules to increase the temperature of water by 1 °C compared to Aluminium which is 0.900 joules to raise the temperature by 1 °C. Consequently, Aluminum will cool easily compare to water which will retain some of it heat longer because it does not heat up quickly like Aluminum.
