A) What assumptions are made about ideal gases. B) if 14g of an ideal gas is added to a 4 dm3 container at 210Kpa pressure and a temperature of 40oc how many moles were added and suggest the identity of the gas.

The two main assumptions that are made about ideal gases are: firstly, that the volume of the gas particles themselves is negligible or zero. So, the entire volume of the container is available. Secondly ...
