I found the answer online.
Answer:
A , 210.3 g
Explanation:
Given data:
Number of moles of SiO₂ = 3.50 mol
Mass of SiO₂ = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of SiO₂ = 60.08 g/mol
by putting values,
3.50 mol = mass/60.08 g/mol
Mass = 3.50 mol × 60.08 g/mol
Mass = 210.3 g
<h2>The required "option is b) Fusion"</h2>
Explanation:
- During fission, the nucleus of higher mass is broken down into the nucleus of lower mass in which a high amount of energy is released.
- During fusion two nuclei combine or fuses to form a larger molecule of higher mass for which a high amount of energy is provided.
- Therefore, the higher mass of a substance is formed with the combination of lower mass of a substance during the process of fusion.
- Hence, the required option is Fusion.
