WebSolution: Step 1: In this step, we have to determine the moles of each element. Number of moles = Mass given in grams Molar mass of element. Number of moles of carbon = 4012. Number of moles of carbon = 3.33 moles. Now; Number of moles of hydrogen = 6.721.01. Number of moles of hydrogen = 6.65 moles. WebAug 23, 2024 · Solution. First, use the density of H 2 O to determine the mass of the sample: 240.0mL × 1.00g mL = 240.0g. Now we can use the definition of ppm: 15.0ppm = massofsolute 240.0gsolution × 1, 000, 000. Rearranging to solve for the mass of solute, masssolute = (15.0ppm)(240.0gsolution) 1, 000, 000 = 0.0036g = 3.6mg.
