To find the mass in grams of 4.22 x 10^23 molecules of salt, we need to know the molecular formula of the salt. Let's assume the salt is sodium chloride (NaCl).
The molar mass of NaCl is 58.44 g/mol, which means that one mole of NaCl has a mass of 58.44 grams.
To find the mass of 4.22 x 10^23 molecules of NaCl, we can use the following steps:
1. Determine the number of moles of NaCl in 4.22 x 10^23 molecules:
4.22 x 10^23 molecules / 6.02 x 10^23 molecules/mol = 0.701 moles
2. Calculate the mass of 0.701 moles of NaCl:
0.701 moles x 58.44 g/mol = 40.9 g
Therefore, the mass in grams of 4.22 x 10^23 molecules of salt (assuming it is NaCl) is 40.9 grams.
