The molar mass of CO2 can be calculated as follows; CO2 — 12 + (16x2) = 12+ 32 = 44 g Therefore molar mass of CO2 is 44 g/mol In 44 g of CO2 there’s 1 mol of CO2 Then 1 g of CO2 there’s 1/44 mol of CO2 Therefore in 78.3 g of CO2 there’s — 1/44 x 78.3 =1.78 mol of CO2
Non metals form ionic bonds by gaining and losing electrons to complete their valence she'll and increase stability.
Metals form covalent bonds by sharing electrons.
