Calculate the number of lone pairs and bond pairs present in 1.1g of CO2. (Use N = 6 x 10^23)
Asked by Theodosia Lourdes | 19 Apr, 2011, 12:44: AM
Expert Answer
44 g of CO2 will have 6.022 x 1023 molecules
1 g of CO2 will have 6.022 x 1023/44 molecules
So,
1.1 g of CO2 = (6.022 x 1023)/x 1.1/44 = 13.82 x 1023 molecules
1 molecule has 4 bond pairs.
So, 13.82 x 1023 molecules will have 55 bond pairs.
Lone pairs wil be zero.
