Standard Temperature and Pressure (STP)

Question 17

How many L does 1 mole of an ideal gas occupy?

Answer 17

22.414 L

Question 18

Molecules neither attract nor repel one another; the volume of the molecule is negligible

Answer 18

Ideal gas

Question 19

What is the value of the R constant

Answer 19

0.082 atm x L/mol x K

Question 20

Density formula

Answer 20

D=m/v … PMM/RT (m is the mss of the gas in g & MM is the molar mass of the gas)

Question 21

Molar Mass of a gaseous substance formula

Answer 21

MM=dRT/P (d is the density of the gas in g/L)
