What is the volume of 6.7 mol of an ideal gas at 145 kPa and 23° Celsius

The volume is 113,72 L

Explanation:

We use the formula PV=nRT. We convert the unit of pressure in kPa into atm; and the temperature in Celsius into Kelvin

101,325kPa1atm

145kPax=(145kPax 1 atm)/101,325kPa=1, 43 atm

0°C= 273K--> 23+273=296K

PV=nRT>V=(nRT)/P

V=(6,7 mol x 0,082 l atm/K mol x 296K)/1, 43 atm= 113,72 L

1.solid

2.carbon dioxide

3.helium

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
