Question

How many moles are present in 585 g of sodium chloride?

Answer 1

To find the number of moles in 585 g of sodium chloride, divide the mass by the molar mass of NaCl (58.5 g/mol), resulting in 10 moles of NaCl.

Step-by-step explanation:

To calculate how many moles are present in 585 g of sodium chloride (NaCl), we must follow two steps in the conversion process:

1. Determine the molar mass of NaCl. Sodium (Na) has an atomic mass of 23.0 u and chlorine (Cl) has an atomic mass of 35.5 u, which adds up to give sodium chloride a molar mass of 58.5 g/mol.
2. Convert from grams to moles using the molar mass of NaCl as the conversion factor. This can be done using the equation: moles of NaCl = mass of NaCl (g) / molar mass of NaCl (g/mol).

By inputting the values into the equation, we get:

moles of NaCl = 585 g / 58.5 g/mol = 10 moles NaCl

The result is that 585 g of sodium chloride is equivalent to 10 moles of NaCl.

Answer 2

Mol NaCl = 585g NaCl (1 mol NaCl)/(58.44g NaCl)

= 10.0 mol NaCl
