Correct Answer: 
No

The correct answer is F, T.

According to the ideal gas law left parenthesis P V invisible times equals n R T right parenthesis, if P, V, and T are the same for two different gases, then n (the number of moles) must be the same. Statement text II end text is therefore true. One mole of text H end text subscript 2 end subscript left parenthesis g right parenthesis has a mass of 2 grams and one mole of  text Ne end text left parenthesis g right parenthesis has a mass of 20 grams. Equal numbers of moles of these gases do not have the same mass. Statement text I end text is therefore false.
