Determine the number of atoms of O in 10.0 g of CO2.

1.37 × 10²³ atoms CO₂

Explanation:

Step 1: Define

Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units

Molar Mass C - 12.01 g/mol

Molar Mass O - 16.00 g/mol

Molar Mass CO₂ - 44.01 g/mol

Step 2: Use Dimensional Analysis

= 1.36787 × 10²³ atoms CO₂

Step 3: Simplify

We have 3 sig figs.

1.36787 × 10²³ atoms CO₂ ≈ 1.37 × 10²³ atoms CO₂

your answers are a,b,,e and f
