2.78*10^2µL → L 6.33*10^1 cm → m 6.48*10^3 Mm → µm 9.4*10^-4 µg → g Convert these units to the desired units
The Safe Drinking Water Quality Standard for nitrate nitrogen (NO3--N) is 10.0 mg/L. Convert this into nitrate (NO3-) in ppm, mmol/L, and normality (N). (Given: N=14, O=16) The highest maximum one-hour ozone (O3; molecular weight = 48) concentration in Houston during 1999-2001 was 175 ppb. Convert this into mg/m3 at STP. The National Ambient Air Quality Standards for 1-hr O3 is 155 mg/m3. (Given: mg/m3 = ppm*MW/22.4).
Show all your work to receive full credit 1. Soil nitrate-N is reported as ppm and the results for the 0 to 6 and 6 to 24 inches in soil depths are 10 and 15 ppm. Convert to lbs. per acre. Assume each 6-inch depth contains 2 million lbs. of soil.
If the concentration of mercury in the water of a polluted lake is 0.33 µg/L of water, what is the total mass of mercury in the lake, in kilograms, if the lake has a surface area of 10.7 mi2 and an average depth of 45 feet? (Hint: get the volume of the lake first.)
The concentration of Cd in lake sediment digestate is 3 µg/L. If 5 g of dry sediment was used, and the total digestate volume is 25 mL, what is the Cd concentration in sediment? Wouldn't the mass of Cd be the 5g?
Convert the following units. Make sure that your answer has the proper number of significant figures. a. 4.8 g/cm3 to kg/m3 b. 941 µm to km. Use scientific notation for your answer. (µ is the prefix "micro" and 1 µm = 1 x 10−6 m) c. The speed of light is 2.9989 x 108 m/s. Convert to miles/hour. Use scientific notation in your answer. d. 782 kg to µg. Use scientific notion for your answer.
