Question

14 gram of co contains how many atoms

Answer 1

Answer:

3.011 × 10^23 atoms

Explanation:

1 mole of CO 28 gram

hence 0.5 mole = 14 gram

1 mole of any substance contain 6.022 × 10^23 atom

no. of atoms in 0.5 mole =

0.5 × 6.022 × 10^23

= 3.011 × 10^23 atoms

Answer 2

Answer:

number of atom = n x sum of subs x 6.02 x 10²³
n = Given Mass/ Molecular Mass
  Molecular Mass => CO = (12 x 1) + (16 x 1) = 28 mol
n = 14g / 28mol = 0.5 g/mol
sum of subs => CO = (1+1) = 2

number of atom = 0.5 g/mol x 2 x 6.02 x 10²³
                           = 6.02 x 10²³ atom

Explanation:

Most people do this question using only => number of atom = n x 6.02 x 10²³ but if you're asked to find the atom in molecule or compound, you should use => number of atom = n x sum of subs x 6.02 x 10²³
sum of subs is the sum of subscripts in the given compound.
