B, I would believe. There are 58, but B is the closest we can get.
Answer:
Explanation:
Molar ratio for Sg : FeS = 1:8
If there are 0.3 moles for Sg
Therefore, 0.3 × 8 =2.4 moles of FeS
Mass = Moles/ Mr
Mr of FeS = 56+32=88
So mass = 2.4/88
Mass= 0.027g
She would be 150 on the moon because the moon has half the mass of earth
Answer:
the molar mass is the mass of a given chemical element or chemical compound divided by the amount of substance
