Dissolver is the answer i think because that is what disovling means
<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
CuSO4. 5H2O(s) → CuSO4(s) + 5 H2O(g)
Here, when we heat copper (II) sulphate pentahydrate, it will turn white in colour from blue colour.
I'm pretty sure its 30.6 grams of CA
