Answer 1

Answer:

Oh i think i know this one uhhh 0.24

Explanation:

Answer 2

Explanation:

Number of moles is defined as mass divided by molar mass of given compound.

Mathematically,        Number of moles = $\frac{mass}{molar mass}$

                                                                = $\frac{0.28g}{28 g/mol}$

                                                                 = 0.01 mol

Therefore, in 1 mole there are $6.023 \times 10^{10^{23}}$ atoms. Hence, calculate the number of atoms in 0.01 mol as follows.

                     $0.01 mol \times 6.023 \times 10^{10^{23}}$

                   = $0.06023 \times 10^{23}$ atoms

Thus, we can conclude that number of atoms in.0.28gm CO is $0.06023 \times 10^{23}$ atoms.
