How is mol calculated?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
What is a gold mass?
The Gold Mass, which follows in the tradition of special Masses for members of different professions, was selected because gold is the color of the hoods worn by individuals graduating with a Ph. D. in science. It is also the color associated with the patron saint of scientists St. Albert the Great.
