the number atoms of chromium and oxygen are 4.8 ×10^10 and 9.6×10^10 respectively.its empirical formula is​

Answer 1

Answer:

HEY MATE HERE IS YOUR ANSWER

Explanation:

Molar ratio of Cr and O = 4.8 x 1010 : 9.6 x 1010 = 1 : 2

Molar ratio of Cr and O = 4.8 x 1010 : 9.6 x 1010 = 1 : 2Hence, empirical formula = CrO2
