During the winter months, many locations experience snow and ice storms. It is a common practice to treat roadways and sidewalks with salt, such as NaCl . If a 11.3 kg bag of NaCl is used to treat the sidewalk, how many moles of NaCl does this bag contain

The moles of NaCL in the 11.3kg bag  is   193.36moles

Explanation:

Given that  a bag of NaCl = 11.3kg

1kg = 1000g

therefore 11.3 kg = 11,300g

Remember that

No of moles = mass of subatance/ molar mass of substance

The molar mass of NaCl = Na + Cl= 22.989769  + 35.453 =58.442769≈ 58.44g/mol

No of moles = mass of subatance/ molar mass of substance

                    = 11300g/ 58.44g/mol  =  193.36 moles

The moles of NaCL in the 11.3kg bag  is   193.36 moles.
