Hey everyone, can any of you explain to me on how to approach this problem? Of course, I will choose best answer.
Problem: Air pollution levels are often measured the same way that you measured parts of drink mix to parts of solution. The EPA has set a safety level for mercury at 2 parts per billion (ppb) by volume. If a person inhales 11,000 L of air a day and 22.4 L contains 6.02 x 10^23 particles of air, calculate the number of mercury particles (atoms) a person may safely inhale daily. From this number of particles, calculate the mass of mercury that could safely be inhalede in a day.
