A chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.07750.0775 L sample, the chemist measures 327327 μg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL. concentration: _____ ppmppm concentration: _____ppb
2. The slopes of the lines in graph 1 can be interpreted as a useful quantity around the lab if you were working with water or one of these solutions. Explain the significance of the slope and how it might be used around the lab. Hint: look at the units and remember when a line is drawn it represents a sort of average as it places about half of the data above and below it due to random errors.

You have just made an aqueous solution of sodium bicarbonate. Now to determine its concentration, you need to figure out what the total volume is. We will assume that this graduated cylinder is divided into 1 mL increments. This means that we can estimate the volume to 0.1 mL to determine significant figures. Include this volume in your data table. we used a Calculate the molarity of your solution using the formula: To clean up the lab, click on the red container to the right of the bench. Data Table Total mass NaHCO3 2.0427 g Moles NaHCO3 0.02431 2.0427g/84.01g/mole L of solution Molarity of solution Calculate the Molarity of your sodium bicarbonate solution.
