Question

the no. of moleculs in 22.4cm cube of ozone gas at STP is ? please ans fast my test is going on​

Answer 1

Answer:

we have to find number of molecules in 22.4 cm³ or 22.4 ml of nitrogen gas at STP.

we have to find number of molecules in 22.4 cm³ or 22.4 ml of nitrogen gas at STP.at standard temperature and pressure (STP), volume of one mole of gas = 22.4 L = 22400 ml.so, number of mole in 22.4ml = 22.4ml/22400ml = 1/1000 = 0.001so, number of moles of nitrogen gas at STP = 0.001now number of molecules of nitrogen gas = number of mole of nitrogen gas × 6.022 × 10²³= 0.001 × 6.022 × 10²³= 6.022 × 10^20hence, number of molecules of nitrogen gas = 6.022 × 10^20

hope it will help

Answer 2

Answer:

the answer is 22·4×10²³
