A standard containing 1.0 ppm NO3-N was treated with a reactive agent to give the absorbance of the 0.30 at 600 nm. A sample was analysed in same manner, which gave absorbance of o.15 at the same wavelength. Quantify the level of NO3-N in this sample: 0.45 ppm NO3 O 0.75 ppm NO3 0.50 ppm NO3 non of above

Therefore, a 100-g sample of water contains 11.2 g of hydrogen atoms and 88.8 g of oxygen atoms. A hydrocarbon is a compound that contains mostly carbon and hydrogen. Calculate the percent composition (by mass) of the following hydrocarbon: CH22 Enter the percentages of carbon and hydrogen numerically to four significant figures, separated by commas. The periodic table will be useful when doing this problem. You can access a periodic table by clicking the "Tools" link in the upper right…
