Question

1. Calculate the weight in grams of 2.30 litres of chlorine gas at NTP.
​

Answer 1

Answer:

In the given electrolysis we have

moles of Mg produced is equals to moles of Cl

2

produced

moles of Mg =

molecularmass

givenmass

=

24

6.5

=0.27

therefore moles of Cl

2

produced = 0.27

at NTP condition volume of 1 mole of gas = 22.4 L

hence, volume of 0.27 mole of Cl

2

= 0.24×22.4=6L
