If the molar mass of a substance is 98.09 g/mol, what is the mass of 3.01 x 10^23 molecules of the substance

[From: ] [author: ] [Date: 13-02-24] [Hit: ]
09 g/mol times 0.500 g/mol = 49.......
49.0 g

this is because of this:

3.01 x 10^23 molecules divided by 6.02 x 10^23 molecules / mole = 0.500 mol

98.09 g/mol times 0.500 g/mol = 49.0 g (to three sig figs)
