Answer: The pressure of the gas is 0.225 atm.
Explanation: To calculate the pressure of the gas, we use Boyle's Law.
Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature.
Mathematically,
Or,
where,
are the initial pressure nd volume.
are the final pressure andvolume
Initial conditions:
Final conditions:
Conversion factor: 1L = 1000mL
Putting values in above equation, we get:
1 mole of propane = 6.02*10^23 propane molecules

Answer:
Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + 2H3PO4
The coefficients are 1, 3, 3, 2
Explanation:
Ca3(PO4)2 + H2SO4 —> CaSO4 + H3PO4
From the above equation,
There are 3 atoms of Ca on the left and 1 atom of Ca on the right. To balance Ca, put 3 in front of CaSO4 as shown below
Ca3(PO4)2 + H2SO4 —> 3CaSO4 + H3PO4
Now, we have 3 atoms of SO4 on the right and 1atom on the left. To balance SO4, put 3 in front of H2SO4 as shown below:
Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + H3PO4
Looking closely, there are 6 atoms of H on the left and 3 on the right. Therefore, it is balanced by by putting 2 in front of H3PO4 as shown below:
Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + 2H3PO4
The coefficients are 1, 3, 3, 2
Answer:
8,403,000 grams
Explanation:
1 kg = 1000 grams, so just multiply by a factor of 1000
