The solubility constant or the Ksp is calculated from the product of the equilibrium concentration of the ions involved. For the compound above, the dissociation would be as follows:
MgF2 = Mg2+ + 2F-1
Ksp = [Mg2+][F-1]^2
6.4x10^-9 = x(2x)^2
x = 1.17x10^-3 mol/L
Answer:
6
6 significant digits
Explanation:
Number of significant digits of a number are the number of digits that carry a relevant contribution to the measurement.
For the case above;
104.100
rule - all digits to the right of the decimal of any number equal or greater than 1 will count as a significant digit.
104.100 --- .100 ( the three digits counts)
And since the the digits to the left are none zero digits, so they all count as significant digits.
104.100 --- 104 ( the three digits counts)
The total number of significant digits,
Since all the digits of the number 104.100 will count as a significant digit.
The number of significant digits is equal to the number of digits in the number.
N = 6
6 significant digits
The positive rod will induce a negative charge on the side of the other rod it is closest to.
