A salt shaker is filled with 25 g sodium chloride. How many mole(s) of nacl does it contain?

AleksAgata [21]

Considering the definition of molar mass, a salt shaker contains 0.43 moles of sodium chloride.

<h3>Definition of molar mass</h3>

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

<h3>Molar mass of NaCl</h3>

In this case, you know the molar mass of the elements is:

So, the molar mass of the compound NaCl is calculated as:

NaCl= 23 g/mole + 35.45 g/mole

Solving:

NaCl= 58.45 g/mole

<h3 /><h3>Amount of moles of 25 grams of NaCl</h3>

Next, you can apply the following rule of three: If by definition of molar mass 58.45 grams of the compound are contained in 1 mole, 25 grams of the compound are contained in how many moles?

$amount of moles=\frac{25 gramsx1 mole}{58.45 grams}$

<u><em>amount of moles= 0.43 moles</em></u>

Finally, a salt shaker contains 0.43 moles of sodium chloride.

A checked exception is known to be often caught at compile time. A runtime or unchecked exception is, is simply known to be at a runtime.

A checked exception is often done using re-throwing but unchecked does not need to be handled.

See full question below

Which of the following statements about checked and unchecked exceptions is true?

A. Checked exceptions are handled by the Java runtime.

B. The compiler ensures that the program is handling unchecked exceptions.

C. The compiler ensures that the program is handling checked exceptions.

D. All exceptions that are descendants of RunTime, Exception are checked exceptions.
