How many moles of nitrous oxide gas (N2O) is contained in 20.0 L balloon at a pressure of 1.09 atm and a temperature of 298K? Ro
prohojiy [21]

Answer:

There are 0,89 moles of nitrous oxide gas  in the balloon.

Explanation:

We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:

PV= nRT ---> n= PV/RT

n= 1,09 atm x 20,0 L /0.082 l atm / K mol x 298 K

<em>n= 0,89212637 mol</em>

A sample of oxygen gas (O2) has a volume of 7.51 L at a temperature of 19°C and a pressure of 1.38 atm. Calculate the moles of O
Maslowich

Answer: 0.43molO₂

Explanation:

The ideal gas law for moles is n=\frac{PV}{RT}. If you did not know, R is the ideal gas constant, 0.0821\frac{L*atm}{mol*K}.

Since the temperature must be in Kelvin, we must convert our given temperature from ℃ to K. 19C+273=292K

Now that we have the temperature converted to Kelvin, we can plug in our information to the ideal gas law for the number of moles.

n=\frac{PV}{RT}

n=\frac{1.38atm*7.51L}{0.0821\frac{L*atm}{mol*K} *292K} =0.43molO_{2}

n=0.43molO_{2}

Therefore, the number of moles is 0.43molO₂.

I hope this helps! Pls mark brainliest!! :)
