A balloon contains 0.40 mol of helium at 300K. calculate
1/ The number of Helium atoms in the balloon
2/ The average kinetic energy of the helium atom in the balloon
3/ The total kinetic energy of the helium atoms in the balloon
I am having a lot of difficulties to manage the ideal gas chapter..Please help me to answer these questions. However the question seems easy and this make me worried as i cannot answer these questions.
My attempt (i don't really know if it is correct as i don't have the asnwer)
1/ 1 mol = 6.02 x 10^23 ataoms
0.4 mol = 6.02 x 10 ^23 x 0.4
