Question

WHich of the following has maximum number of molecules a) 7 grams of nitrogen b)23 grams nitrous oxide c)2 grams hydrogen d) 16 grams oxygen

Answer 1

Answer:

c is the answer

Explanation:

7 g of nitrogen= 0.5 mole

23g of NO2= 0.5 mole

2 g of hydrogen = 1 mole

16 g of O2= 0.5 mole

Answer 2

Answer:

(C)

Explanation: no. Of moles = given mass/molecular or molar mass

If you put 1) nitrogen = 7 /14 is .5moles

2) nitrous oxide 23 by 39 give you .58 malls

3) hydrogen 2 by 2 will give you one mole

4) oxygen 16 by 32 will give you 0.5 moles
