How was this problem calculated (chemistry – relative atomic mass)?
I've tried a few things, but everything, except for the 24 before the decimal point, isn't the same as in the given solution. Can anyone tell me how to solve this problem, since I have no other way to get the information from others.
Correction

Thank you. However, there should be 0.1•24.99 and not 0.01 or not
typos, sorry.
