Answer:
Explanation:
The fundamental units of a measurement is known as its base unit. The units of these substances serves as the base through which other quantities depends. Examples of such quantities are mass, length, time, electric current, temperature, amount of substance and luminous intensity.
Derived units are those that results from the combination of the fundamental or basic units. Examples of derived quantities are force, volume, density, pressure e.t.c.
Derived units of Density:
kgm⁻³
gcm⁻³
Derived unit of volume:
m³
cm³
mL
L
dm³

It has been given that,
NO + Ag⁺ → NO₃⁻ + Ag
The oxidation half reaction is,
NO + Ag⁺ = NO₃⁻ + Ag
The reduction half reaction is,
Ag⁺ +e⁻ → Ag
The overall balanced reaction is:
3Ag⁺ + NO + 2H₂O → 3Ag + NO₃⁻
Use the grams to moles first. The molar mass of sodium is 22.99g, so 10/22.99 ≈ 0.43 moles. The use moles to atoms conversions. 0.43 x (6.022 x 10^23), which would be about 2.62 x 10^23 atoms in 10g of sodium.
All of the above so it would be c
