Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 4.50 moles of magnesium perchlorate, mg(clo4)2. express the number of moles of mg, cl, and o atoms numerically, separated by commas.

4.50, 9.00, 36.00 First, count the number of atoms of each element in a single molecule of Mg(ClO4)2. Mg = 1 atom Cl = 1 * 2 = 2 atoms O = 4 * 2 = 8 atoms Now multiply the number of atoms of each element per molecule of the compound by the number of moles of the compound. So Mg = 1 * 4.50 = 4.50 Cl = 2 * 4.50 = 9.00 O = 8 * 4.50 = 36.00 So the answer is 4.50, 9.00, 36.00

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
