The molecular weight is the same as molecular mass. You find this by using the periodic table
The molar mass of Mg(NO3)2 is 148.3
The answer is 1.164451827 moles
A. Jupiter. is the correct answer. Mark as brainliest please.
Acetic Acid has two C atoms, four H atoms, and two O atoms, so the molecular formula is C2H4O2.
