Answer:
Cr203
Explanation:
(1.00 g Cr) / (51.996 g Cr/mol) = 0.019232 mol Cr
(0.461 g O) / (15.99943 g O/mol) = 0.028814 mol O
Divide by the smaller number of moles:
(0.019232 mol Cr) / (0.019232 mol = 1.000
(0.028814 mol O) / (0.019232 mol = 1.498
In order to achieve integer coefficients, multiply by 2, then round to the nearest whole number to find the empirical formal:
Cr2O3
