1) Find the mass of 2.7 moles of NaCl.

Answers

Answer 1

Answer:

157. 788 grams

Explanation:

number of moles = mass/molar mass.

hence the mass = molar mass × number of moles

m = 58.44 × 2.7 = 157.788 grams

Answer 2

The term mole concept is used here to determine the mass of sodium chloride. The mass of 2.7 moles of NaCl is 157.78 g.

What is a mole?

One mole of a substance is defined as that quantity of it which contains as many entities as there are atoms exactly in 12 g of carbon - 12. The formula used to calculate the number of moles is:

Number of moles = Given mass / Molar mass

The mole concept is a convenient method to express the amount of a substance. The elementary particles in moles may be atoms, ions, molecules etc.

The molar mass of NaCl = 58.44 g/mol

Here the number of moles of NaCl = 2.7

Mass = Molar mass × Number of moles

58.44 g/mol × 2.7 = 157.78 g

Thus the mass of NaCl is 157.78 g.
