HELP plis ! Find the molar masses of the following compounds: SHOW ALL WORK!!!

1) LiI. Li. 7 + I 127

134g/mol

2) PbCO4

Pb =. 1 x 207 =207

C = 1 X 12 = 12

O = 4 x 16 = 64

283 g/mol

3) Mg(OH)2

Mg= 1x 12 = 12

O= 2 x16 =32

H= 2x1= 2

46 g/mol

4) K3PO4

5) (NH4)3PO4

6) C12H22O11

7) Fe2(SO4)3

8) Na3P

9) AgF

10) NH4C2H3O2

What is the maximum amount of al2(so4)3 which could be formed from 15.84 g of al and 12.89 g of cuso4?

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?
