Which of the following pairs contain equal number of atoms?

1.	Which of the following pairs contain equal number of atoms?
Answer» 22.4 L (STP) of nitrous oxide and 22.4 L of nitrifc oxide 1 millimole of HCl and 0.5 millimole of `H_(2)S` 1 MOLE of `H_(2)O_(2)` and 1 mole of `N_(2)O_(4)` 11.2 cc (STP) of nitrogen and 0.015g of NITRIC oxide Solution :d) Number of atoms in `N_(2)` `=(11.2 XX 10^(-3) xx 6.023 xx 10^(23) x 2)/(22.4) = (6.023 xx 10^(20)` Number of atoms in NO = `(0.015 xx 2 xx 6.023 xx 10^(23))/(30)` `=6.023 xx 10^(20)`
