The area of one of the walls of container is 3cm^2 . 10^23 Number of molecules are incident on it every second at an angle of 45^@ . What is the pressure exerted on the wall if the velocity of each molecule is 10^5 cm.s^-1 and it mass is 3.32 times 10^-24 g ?

How many molecules are there in a 3.46 g sample of hydrogen chloride, HCl? Note: The number of molecules in a sample is related to moles of compound (1 mol HCl = 6.023 xx 10^(23) HCl molecules). Therefore if you first convert grams HCl to moles, then you can convert moles to number of molecules).
