Question

Find the mass of
1 mole of nitrogen atom
8 mole of carbon atom
0.2 mole of oxygen atom
1 atom of carbon

Answer 1

hey mate !!! ❤✌
here's ur answer ⤵⤵⤵⤵

➡ Molar mass of a substance = 1 Mole
molar mass of nitrogen = 14g
➡ Molar mass of carbon = 12g
Mass of 1 Mole = 12g
Mass of 8 Mole = 12×8
=96
➡ Molar mass of oxygen = 16g
Mass of 1 Mole = 16g
Mass of 0.2 Mole = 16×2/10
= 3.2 g
➡ The mass of 1 mole of C is 12 g and 1 mol has 6.022 *10^23 atoms. This means that's 6.022*10^23 atoms of C taken together weigh 12 g.
❄ Thus the mass of 1 atom of C has to be 12/(6.022*10^23)
