A 5.13g sample of a solid containing Ni is dissolved in 20.0mL water. A 5.00mL aliquot of this solution is diluted to 100.0mL and analyzed in the lab. The solution was find out to contain 5.09 ppm Ni. Find the molarity of Ni in the 20.0mL solution.
a. Find out molarity of Ni in the 20.0ml
b. Find out mass in grams of Ni in original sample
c. Find out the weight % in original sample
