Explanation:
<h3>Answer:</h3>
2.6 × 10⁻³ g (Or) 0.0026 g
<h3>Data Given;</h3>
Mass of Oxygen = 1.38 × 10⁻³ g
Mass of Silicon = 0.00122 g = 1.22 × 10⁻³ g
<h3>Solution:</h3>
The total weight of grain of sand is calculated by adding the masses of Oxygen and Silicon as,
Total Weight = Mass of Oxygen + Mass of Silicon
Putting values,
Total Weight = 1.38 × 10⁻³ g + 1.22 × 10⁻³ g
Total weight = 2.6 × 10⁻³ g
Or,
Total weight = 0.0026 g
