Let's summarize the given data.
00:04
Temperature is 44 .0 c.
00:09
Pressure is 0 .870 a.
00:18
Mass of carbon is 91 .5 g.
00:27
The task is to find the volume of oxygen gas that is needed in liters.
00:38
Let's write reaction equation.
00:42
Carbon plus oxygen gas equal to carbon dioxide gas.
00:49
This reaction is balanced.
00:52
Next, let's find the number of moles of carbon.
00:55
We know that molar mass of carbon is 12 .01 g per mole.
01:06
So now we can find the number of moles of carbon.
01:10
Mass 91 .5 g divided by molar mass 12 .01 g per mole.
01:22
And we obtain 7 .6187 moles...
