Use the formula grams divided by moles is equal to molar mass over one. the molar mass of mg is 24.3050.
19.04 = 24.3050 * x
x= 0.7833779058

Reply to e-mail: You got it.

Get a periodic table. It lists the atomic mass is the grams per mol. It is a ratio and proportion problem. Another way to put it is in fraction form. That's it. X = 19.04g Mg * Mol / what you look up.
