11. If there are 8.24 x 1022 molecules of NaCl in a salt shaker, what is the mass of the salt?
vlada-n [284]

Answer: 8.12 g NaCl

moles of NaCl:

8.24x10²² molecules NaCl / 1 mole NaCl/ 6.022x10²³ molecules NaCl

= 0.14 mole NaCl

Next convert moles to grams NaCl using its molar mass;

0.14 mole NaCl x 58g NaCl / 1 mole NaCl

= 8.12 g NaCl
