Well it’s the first answer couches
Answer:
Different substances have different molecular masses. Thus, equal masses have different numbers of atoms, molecules, or moles. On the other hand, equal numbers of moles of different substances have different masses.

Explanation:
Cholesterol concentration = 27 mg/ 232 mL
Change unit mg/ml to kg/m³
1 kg = 1000 g
1 g = 1000 mg
1 kg = 1000000 mg
1 kg = 10⁶ mg
10⁶ mg = 1 kg
1 mg = 10^-6 kg
m³ = 1000 L
1 L = 1000 mL
m³ = 1000000 mL
m³ = 10⁶ mL
10⁶ mL = m³
1 mL = 10^-6 m³
Cholesterol concentration = 27 mg/ 232 mL
27 × 10^-6 kg/ 232 × 10^-6 m³
= 27/232 kg/m³
Pure water would be classified as non-conductor since it does not allow the flow of current into the solution. It does not contains any ions or free electrons so it cannot allow the flow of current into the system. It can allow current only when any impurities is present like salts.
