vivado [14]3 years ago
6 0
In 1 mole = 6.022 * 10^23 molecules of CO2 
In 1.75 mole = 6.022 * 10^23 * 1.75 
=10.53 * 10^23.
I hope this helps.

0.65 moles of O2 originally at 85°C is cooled
soldier1979 [14.2K]

Answer:

2.09 atm

Explanation:

We can solve this problem by using the equation of state for an ideal gas, which relates the pressure, the volume and the temperature of an ideal gas:

pV=nRT

where

p is the pressure of the gas

V is its volume

n is the number of moles

R is the gas constant

T is the absolute temperature

In this problem we have:

n = 0.65 mol is the number of moles of the gas

V = 8.0 L is the final volume of the gas

T=40C+273=313 K is the temperature of the gas

R=0.082 atm L mol^{-1} K^{-1} is the gas constant

Solving for p, we find the final pressure of the gas:

p=\frac{nRT}{V}=\frac{(0.65)(0.082)(313)}{8.0}=2.09 atm
