At NTP, the ratio of molecules in 1cc of oxygen to that in 1cc of hydr

1.	At NTP, the ratio of molecules in 1cc of oxygen to that in 1cc of hydrogen is : (a) 1 : 1 (b) 1 : 4 (c) 1 : 16 (d) 1 : 2
Answer» Correct option (a) 1 : 1 Explanation: From the formula, the number of molecules in V litres of gas at NTP is = NV/22.4 It represents that at NTP, all the gases have same number of molecules in same volume. Hence, ratio of molecules in both cases is 1 : 1.

Answer»

Correct option (a) 1 : 1

Explanation:

From the formula, the number of molecules in V litres of gas at NTP is = NV/22.4

It represents that at NTP, all the gases have same number of molecules in same volume. Hence, ratio of molecules in both cases is 1 : 1.
