Answer 2

$\huge{\textbf{\red{Answer is here.}}}$

H. The number of molecules in 22.4 cm of nitrogen gas at STP is:

Answer:- (b). 6.022 × 10^23 molecules because as we know that the one mole is equal to the 22.4 litres, as in volume it is 22.4 cm³, So that the number of molecules in 22.4 cm of Nitrogen gas at STP is (b). 6.022 x 10^23.

As we also know that 6.022 x 10^23 is also called the avagadro 's number. As we also know that one mole of any elements are in volume is 22.4 cm³ or in quantity is 22.4 litres in the terms of the STP.
