In the diagram below, two identical objects are released from rest at the starting position. Object 1 was released first and som
etime later Object 2 was released. The diagram below shows the positions of Objects 1 and 2 a short time after both were released.

A.Both objects have the same amount of kinetic energy.
B.Object 1
C.Object 2
D.Neither object has any kinetic energy.

The standard ambient temperature and pressure are
Temperature =298 K
Pressure = 1atm
The density of gas is 1.5328 g/L
density = mass of gas per unit volume
the ideal gas equation is
PV = nRT
P = pressure = 1 atm
V = volume
n = moles
R= gas constant = 0.0821 Latm/mol K
T = 298 K
moles = mass / molar mass
so we can write
n/V = density / molar mass
Putting values
Thus molar mass of gas is 37.50g/mol
