Sn is +4
CrO4 is -2
thus the formula is
Sn2(CrO4)4
jujula is wrong, no offense though...

I am just taking my test on this tomorrow, and ad far as I know there wouldn't be a "imperical formula," or I haven't learned about one. Teroy should be right. I'll try to break it down :)
1. Find your cation and anion. (cation is positive ion, anion is negative ion.) Tin= Sn with a charge of 4+, chromate=CrO4 with a charge of 2-
2. use the cross over method, which is basically switching charges and making them subscripts. That's why Sn4(CrO4)2 becomes Sn2(CrO4)4
*make sure that 4, which is a subscript of chromate, doesn't get separated from it!! That's why you put it in parenthesis and than only switch the 4 and 2 around. My teacher said subscripts are like limbs;vitally important. (Yes, she's crazy. Yes, she says stuff like that ALL the time! XD)

CrO4 is the chromate ion with a 2- charge. So aluminum chromate is Al2(CrO4)3

Teroy has never heard of the imperical formula lol jujula is correct
