What are the concentrations of each of the ions in a saturated solution of PbBr2, given the Ksp of PbBr2 is 2.1 x 10^-6? I get stuck in solving this question when I get to the equation 4(x^3)=2.1 x 10^-6 and I don't know how to get to the answer x = 8.07 x 10 ^-3 M which is supposedly the concentration of Pb 2+. Real

The standard deviation of a data set is a measure of the 'spread' of a distribution of data or other numerical values; it is a measure of variability within a particular data set. To calculate standard deviation of a sample, generally the variance of the sample is first calculated. The variance is the average squared deviation o
