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

Answer:
Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster.
