//Input data
T=300;//The given temperature in K
M=32;//Molecular weight of oxygen
R=8.3*10^7;//The Universal gas constant in ergs/g mol-K
//Calculations
E=(3/2)*R*T;//Total random kinetic energy of 1 g molecule of oxygen in ergs
v=((E)*(2/M))^(1/2);//The required speed of one gram molecule of oxygen in cm/s
//Output
printf('The required speed of one gram molecule of oxygen is v = %3.2g cm/s ',v)
