4 mg of zinc found in 100g of oysters what is the ppm?
In other words, if you take the ratio between the mass of the solute and the mass of the solution, both expressed in grams, and multiply it by
This is exactly how you would get percent concentration, the only difference beingthat you need to multiply that ratio by
So, your concentration in ppm is
#(4 * 10^(-3)color(red)(cancel(color(black)("g"))))/(1 * 10^2color(red)(cancel(color(black)("g")))) * 10^6 = 4 * 10^1 = color(green)("40 ppm")#
