How many grams would 8.88 x 1029 atoms of NaCl be equivalent to?
olasank [31]

Answer:

8.65x10 7 grams of nacl

Explanation:

There are 6.02x10 23 atoms per one mol

so

8.88x 10 29 x (1/6.02 x 10 23)

Will give us mols of NaCl

to go from mols to grams we multiple mols by molar mass

so

1.48x10 6 mols of Nacl x 58.44 g/mol = 8.65x10 7 grams of nacl which can be converted to

86500 kg
