A chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.0950 L sample, the chemist measures 484 μg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL.
