What is the mass of 3.25 moles of sodium hydroxide (NaOH)?

Answers

Answer:

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

The statement of the mass of sodium hydroxide (NaOH) is "130 g."

What is mass?

A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.

In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.

Mole to gram conversion factor,

[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]

Mass of NaOH comes out to be,

[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]

= 129.99 g

= 130 g

Hence the correct answer is 130 g.
