In order to control corrosion, the system must take a variety of additional measures if lead concentrations reach an action threshold of 15 ppb or copper concentrations exceed an action level of 1.3 ppm in more than 10% of measured customer taps.

marta [7]

Answer:

0.0123 moles

Explanation:

Concentration = Moles / Volume of solution

or you can rearrange the formula to get

Moles = concentration (moles/liter)  x  volume of solution (liter)

First convert your volume to L instead of mL.  35mL = 0.035L

moles  =  0.350 moles/liter   x    0.035 liter  (liters cancel out)

moles = 0.0123
