Answer 1

yeah that works much better.

so look at the last two lines, you have:

M=172.8 = 173
M= 1.7g

you went from 173 g to 1.7 g, that's not possible.

you need to convert 173 g to kg (divide by 1000)

or you can use scientific notation

Answer 2

both would be in metric units

0.17 kg or \(1.7*10^2~g\)
