Respuesta :

P = 600 mmHg
V = 2.2 L
T = 85°C
R = 0.08206 L atm / mol K
n = ?

I would start by converting the P from mmHg to atm, since our gas constant R uses atm.

600 mmHg • 1 atm / 760 mmHg = 0.789 atm = P

Then I would convert T from Celsius to Kelvin, since our gas constant R uses Kelvin.

85 + 273 = 358 K

Now you can solve PV = nRT for n, giving you:
n = PV/RT
n = (0.789 atm)(2.2 L) / (0.08206 L atm / mol K)(358 K) = 0.059 moles of gas

We have that for the Question "How many moles of a gas are in a 2.2-liter balloon at 600 mmHg and 85 C." it can be said that Moles of gas is

n= 0.059 moles of gas

From the question we are told

How many moles of a gas are in a 2.2-liter balloon at 600 mmHg and 85 C. Also asks to identify the P, V, N, R, and T. If unknown then put "?"

Generally the equation for the   is mathematically given as

[tex]P=\frac{600}{760}\\\\P=0.789atm[/tex]

Therefore

[tex]n=\frac{PV}{RT}\\\\Therefore\\\\n=\frac{PV}{RT}\\\\n=\frac{0.789*2.2}{0.08206*(85 + 273)}\\\\[/tex]

n= 0.059 moles of gas

Therefore

Moles of gas is

n= 0.059 moles of gas
