How many molecules are present in 22400 ~cm ^3 of a gas at STP?
Options
- A22.4 10²⁰
- B6.022 10²³
- C6.022 10²⁰
- D22.4 10²³
Correct answer
B. 6.022 10²³
Step-by-step solution
aligned & Number of moles of gas = Volume 22.4 ~L [22400 ~cm ^3=22.4 ~L ] & = 22.4 22.4 =1 & Number of molecules = moles N _ A & =6.022 10²³ aligned
