Question

Ce cantitate de tetraclorura de carbon contine 27,099 ori 10 la puterea 23 legaturi covalente sigma??

Answer 1

1mol CCl4 contine  6,023*10²³ molecule CCl4........4*6,023*10²³ legaturi σ
x moliCCl4...................................................................27,099*10²³ legaturi σ

x=27,099*10²³/24,092*10²³=1,12 moli CCl4
                                             m=n*M=1,12moli*154g/mol=........
