22.4 liters of a gas at a constant temperature of zero Celsius and a pressure of 1 atmosphere is compressed to a volume of 6.2 l
zhannawk [14.2K]
<h2>Hello!</h2>

The answer is: The new pressure of the gas is 3.6 atm.

<h2>Why?</h2>

From the statement we know that the gas is kept at a constant temperature of 0°C, so, if the gas keeps a constant temperature we can use the Boyle's Law to solve this problem.

The Boyle's Law states that:

P_{1}V_{1}=P_{2}V_{2}

Where,  

P is the pressure of the gas.

V is the volume of the gas.

So, the given information is:

V_{1}=22.4L\\P_{1}=1atm\\V_{2}=6.2L

Now, substituting it into the Boyle's Law equation to calculate the new pressure, we have:

P_{1}V_{1}=P_{2}V_{2}\\\\1atm*22.4L=P_{2}*6.2L\\\\P_{2}=\frac{1atm*22.4L}{6.2L}=3.6atm

So, the new pressure is 3.6 atm.

Have a nice day!

Calculate the molar mass<br> FeCl3 <br> Fe2(SO4)3 <br> PbO <br> PbO2 <br> Pb3O4
Anvisha [2.4K]
To find molar mass: look for each element on the table and find their atomic masses. Then add each atomic mass to find the molar mass. If there is a subscript then that means that there is 3 of that number. For atomic mass round to the nearest hundredths
FeCl3= 162.2
Fe2(SO4)3= 354.88
PbO=223.2
PbO2 = 239.2
Pb3O4=685.6
