A helium-filled balloon contains 130 mL of gas at a pressure of 0.97 atm. What volume will the gas occupy at standard pressure?
jonny [76]
Boyle's Law 
 G:  V1= 130 mL   
       P1= 0.97 atm P2= 1 atm (standard pressure)
 
 U: V2=?
 F: V2 = V1 P1/P2
 S: V2 = (130 mL) (0.97 atm) / 1 atm
 Answer : V2 = 126.1 mL volume of the gas occupy @ STP

Wat are the five assumption of kinetic therory of gases​
il63 [147K]

Answer:

The five assumption of Kinetic molecular theory are given below.

Explanation:

Kinetic molecular theory of gasses stated that,

1) Gases consist of large number of smaller particles which are distance apart from each others.

2) The gas molecules collide with each other and also with wall of container and this collision is elastic.

3) Gas molecules are in continuous random motion and posses kinetic energy.

4) The forces of attraction between gas molecules are very small and considered negligible.

5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.

A sample of sulfur hexafluoride gas occupies a volume of 9.10 L at 198ÁC. Assuming that the pressure remains constant, what temp
alexandr1967 [171]
  As we know that
<span>V1/T1 = V2/T2 
V1 = 9.10 L 
T1 = 471 K 
V2 = 2.50 L 
T2 = 2.5 x 471 / 9.10 = 129.3 K 
T2 = 129.3 - 273 =
