How many molecules of sucrose c12h22o11 are there in 454 grams of sucrose

c(C12H22O11) = 342.3 g/mol

454 g / (342.3 g/mol) = 1.326 mol

1.326 mol * 6.022*10^23 molecules/mol = 7.985·10^23 molecules

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.
