Question

Density of CCI vapour is 6.87 g/L at STP. What is the number of chlorine atoms present in 100 mL of it
at the same temperature and pressure ?​

Answer 1

Answer:

8.7 x 10²¹

Explanation:

weight of CCL vapour in hundred ml = 6.87 x 0.1

= 0.0145

atoms of CCL = 0.0145 x 6.022 x 10²³

= 8.7 x10²¹
