Answer:
umm 6.0?
Step-by-step explanation:
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
2(4x - 7) -1 = 11
8x - 14 -1 = 11
8x - 15 = 11
+ 15 + 15
8x = 26
/8 /8
x = 3. 25 ------> Rounded: 3.30
