1.	B. Potassium dichromate (K,Cr,0,),percentage composition
Answer» Potassium Dichromate is K2CR2O7 total MASS = 292 % of K = 39x2/292 = 26.7% % of CR = 51x2/292 = 34.9% % of O = 16x7/292 = 38.4%

Answer»

Potassium Dichromate is K2CR2O7

total MASS = 292

% of K = 39x2/292 = 26.7%

% of CR = 51x2/292 = 34.9%

% of O = 16x7/292 = 38.4%
