Question

calculate the molar mass of calcium sulfide for me pleasee

Answer 1

First refer to the Periodic Table,
RAM for CA = 24.31
RAM for S = 32.07

Formula of calcium sulfide is CaS

Hence, 24.31+32.07 = 56.38 g/mol

Answer 2

and aluminum sulfate plss and thankyou

Answer 3

@asian . do you know how to make the chemical compound formula, actually?

Answer 4

Aluminium sulphate = Al(SO4)3

RAM of Al = 26.98
RAM S = 32.07
RAM O = 16.00

Hence;
26.98 + 3(32.07) + 3(16.00 X 4)
= 315.19

Answer 5

i thought it was 342
