Question

10.7 L O 22.4 L 47.0 L 82.0L 2. What is true at STP? (3 points) O Temperature is 300 Kelvin. O One mole of gas occupies a volume of 22.4 liters O Pressure is 101 atmospheres. O Volume is 24 liters. 3. Under certain conditions, neon (Ne) gas diffuses at a rate of 4.5 centimeters per second. Under the same conditions, an unknown gas diffuses at a rate of 10.1 centimeters per second. What is the approximate molar mass of the unknown gas? (3 points) O 45 g/mol O 9.8 g/mol O 4.0 g/mol O 2.0 g/ Directions Start: 7:01 PM

Explanation / Answer

Ans 1. C . 47.0 L

1 mole of any ideal gas occupies 22.4 L volume at STP according to Avagadro's law

so 2.1 mole of Chlorine gas will occupy 2.1 x 22.4 = 47.04 L of volume
