CaSO4.XH2O looses 6.2% of water upon heating.The value of x will be(1) 2(2) 3(3) 4(4) 1/2
Answers
Answer:
The answer is 1/2.
Step-by-step explanation:
As we know that:
Molecular weight of water x (x) / Mass of salt
The mass of salt to be taken has to be that of before water of crystallisation. here it is CaSO4.
Thus,
18x / 40 + 32 + 64 = 6.2%
18x / 136 = 6.2 /100
Solve for x:
18x / 136 = 6.2/100
18x = 6.2 / 100 x 136
18x = 8.4
x = 8.4 / 18
x = 0.46 ~ 0.5
x = 1/2
Thus the value of x will be 1/2.
