Answer:
172 g/mol
Step-by-step explanation:
CaSO4 . 2H2O
Atomic mass of
Ca = 40
S = 32
O = 16
H = 1
Molar mass = 40 + 32 + (16×4) + 2{(1×2)+16}
= 72 + 64 + 2(18)
= 136 + 36
= 172 g/mol
Answer:

2y^3 / x^2 - y^2
hope this helps and is right. p.s i really need brainliest :)
if my answer is wrong then I am incredibly sorry!
