Which of the following best defines insulator?
valkas [14]

C.) a substance with a low ability to conduct energy

Explanation:

The statement that best defines insulators is that it is a substance that has low ability to conduct energy.

Insulators resist the movement of mostly electrical and thermal energy.

They have unique properties that makes them so.

  • Insulators are substances that do not conduct heat and electricity.
  • Both their solid and molten form lacks the capability of electrical and thermal conduction.
  • Some substances can only conduct when molten or liquid.
  • Conductors are materials that allows for the passage of electrical and heat energy.
  • Most conductors are usually salts, ionic compounds and metals.
  • Non-conductors like insulators are usually plastics and woods.

A doctor recommends no more than 2.00 grams of sodium chloride (NaCl, 58.55 g/mole) per day. Potato chips have 250.0mg of NaCl p
Alexeev081 [22]

Answer : The number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39

Explanation :

First we have to calculate the moles of NaCl.

\text{Moles of NaCl}=\frac{\text{Mass of NaCl}}{\text{Molar mass of NaCl}}

\text{Moles of NaCl}=\frac{250.0mg}{58.55g/mol}=\frac{0.250g}{58.55g/mol}=0.004269mol

Now we have to calculate the number of servings.

As, the number of serving in 0.004269 moles of NaCl = 1 serving

So, the number of serving in 0.0230 moles of NaCl = \frac{0.0230}{0.004269}=5.39 serving

Thus, the number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39
