Answer 2

Answer:

calculate the mass of one molecule of water ?

Explanation:

Determine average mass of one molecule of water: 18.015 g/mol / 6.022 x 1023 molecules/mol = 2.99153 x 10¯23 g/molecule.

Determine number of molecules in one drop of water: 0.010 g / 2.99153 x 10¯23 g/molecule = 3.3 x 1020 molecules (to two sig figs)
