How many molecuels and atoms of oxygen are present in 5.6 litres of oxygen (O_(2)) at NTP. |
|
Answer» Solution :We KNOW that 22.4 litres of oxygen at NTP CONTAIN `6.02xx10^(23)` molecules of oxygen. So, 5.6 litres of oxygen at NTP contain. `=(5.6)/(22.4)xx6.02xx10^(23)` molecuels ltbr. `=1.505xx10^(23)` molecules 1 molecule of oxygen contain=2 ATOMS of oxygen. So, `1.505xx10^(23)` molecules of oxygen contain. `=2xx1.505xx10^(23)` atoms ltbr. `=3.01xx10^(23)` atoms. |
