A. mols Mg = grams/molar mass = aprox 0.0082 but you need to redo all of these since I've estimated.
B. mols Cl2 = grams/molar mass BUT mols Cl ion is grams/atomic mass or approx 0.0028
C. 0.0082/0.0028 = 2.93
D. 0.0028/0.0028 = 1.00
E. D is rounded to 1.00; C is rounded to 3.00 empricial formula is Mg3Cl
F. MgCl2.
please HELP!!
mass of magnesium chloride =.2
mass of chlorine in magnesium chloride =.1
A)moles of magnesium?
B)moles of chlorine?
C)moles of magnesium divided by the smaller number of moles?
D)moles of chlorine divided by the smaller number of moles?
E)experimental empirical formula of magnesium chloride?
F) true empirical formula of magnesium chloride?
