Question

calculate the relative molecular mass of the following

1). ethanol (C2 H5 OH)
2). potassium permanganate
(K Mn O4)
3). potassium dichromate
(K2 Cr2 O7)
4). sucrose (C12 H22 O11)​​

Answer 1

1) C×2 + H×5 + O+H = 46

2) K + MN + O×4 = 158

3) K + Cr ×2 + O×7 = 294

4) C × 12 + H × 22 + O ×11 = 342

Don't copy as it is write with the proper answers
