Question

calculate the molecular mass of aluminum sulphate​

Answer 1

Answer:

Al2(So)4

atomic mass of

aluminum 27

Sulphur 32

oxygen 16

total mass

27*2+32*4+16*4

54+128+64 = 246

Answer 2

Answer:

342 u

Explanation:

Atomic mass of Al= 27, atomic mass of S = 32, atomic mass of O=16                  Then, molecular mass of Al2(SO4)3 = 27x2+32x3+16x4x3 = 54+96+192 = 342u
