1) The maximum allowable concentration of lead in drinking water is 9.0 ppb. (a) Calculate the molarity of lead in a 9.0-ppb solution. What assumption did you have tomake in your calculation? (b) How many grams of lead are in a swimming pool containing 9.0 ppb lead in 60 m3 of water?
Part B: Parts Per Units Parts per million (ppm) and parts per billion (ppb) are common units for environmen- tal samples. The calculations are very similar to the percentage units. (which are es- sentially parts per hundred units). The mass units must be the same for the numerator and denominator, so these units cancel during the calculations. units; show all Please answer the following questions involving the parts per of your calculations. 7. A sample of river water was analyzed,...
If a 150 mL sample of water from a lake is found to contain 1.7 μg of arsenic (As), what is the concentration of arsenic in the sample in parts per billion (ppb)?
A 1435 mL sample of drinking water was found to contain 67.0 mg of lead. Calculate the concentration of lead in milligrams per liter. lead concentration: m g/L Calculate the percent mass per volume, % (m/v), of a dextrose solution containing 8.00 g of dextrose in 2.00 x 10 mL of solution. Note that mass is not technically the same as weight, but the abbreviation % (w/v) is often used interchangeably with % (m/v). percent mass per volume concentration: %...
A 1025 mL1025 mL sample of drinking water was found to contain 33.0 mg33.0 mg of lead. Calculate the concentration of lead in milligrams per liter.
The concentration of chlorine in the air is measured in parts per billion (PPB) and recorded to the nearest PPB. State the sample space
Concentrations of dissolved solids in water are often reported in parts per million (ppm) or parts per billion (ppb). One part per billion of a solute is equivalent to 1 ug (microgram) of that solute dissolved in 1 litre of water (i.e., 1 ppb = 1 pg/L). The toxic water crisis in Flint, Michigan in 2015 yielded test results of up to 1051 ppb of lead dissolved in tapwater. (The maximum allowable concentration set by Health Canada is 5 ppb)....

The chemical trichloroethylene (TCE) is a colorless liquid found in very low concentration in drinking water. The EPA has set a maximum concentration of TCE in drinking water at 5 ppb. Consuming water on a regular basis that contains higher concentrations can lead to cancer. (a) What is the ppb concentration in a 200.0−L (200.0 kg) sample of water that contains 0.15 mg TCE?
If the drinking water supply for a municipality has a reported concentration of lead at 14.0 ppb, what would the total lead exposure for an individual be if the person drank an average of 1.80 liters of water per day?
