A farmer applies 1655 kg of a fertilizer that contains 10.0% nitrogen to his fields each year. Fifteen percent (15.0%) of the fertilizer washes into a river that runs through the farm. If the river flows at an average rate of 0.195 cubic feet per second, what is the additional concentration of nitrogen (expressed in milligrams of nitrogen per liter) in the river water due to the farmer's fertilizer each year?   .              mg/L

Dimensional Analysis is a way of doing numerical "book-keeping" when converting quantities or performing calculations. • When converting quantities from one unit to another, conversion factors are used. Solving with Dimensional Analysis and Multiple Units: If I am in Canada where the price of gas is $1.022 USD·L1, how much will it cost me to fill up my gas tank if I travelled 125 km? • Let's also assume that my car gets an average of 30.0 miles/gallon.

O MEASUREMENT Adding or subtracting and multiplying or dividing measurements A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.5 g • She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 36.669 g. • She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 37.11 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. g mL Explanation -1 Check 99+ 0/5 VUDU © 2023 McGraw Hill LLC.

Convert the following measurement. 3 g kg 1.6 x 10 x10 mol · L mol · dL

Convert the following measurement. -5 kg, g 7.6 x 10 x10 mol-dL mol·L X

Blood alcohol content is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100 mL of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume. what is the total mass of alcohol (in grams) that is present for the same adult male whose total blood volume is 5.6L?

A chemist prepares a solution of silver perchlorate (AgC104) by measuring out 1.2 kg of silver perchlorate into a 450. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's silver perchlorate solution. Be sure your answer has the correct number of significant digits. mol/L

Which piece of equipment would you use to measure 7.10 mL of CuSO4 (aq)?

A chemist prepares a solution of silver(I) nitrate AgNO3 by measuring out 6.4102 x 10^2 μmol of silver(I) nitrate into a 450.mL volumetric flask and filling the flask to the mark with water.  Calculate the concentration in mol/L of the chemist's silver(I) nitrate solution. Round your answer to 2 significant digits.

One of the Ionic compounds in sports drinks is potassium di hydrogen phosphate. The label on one of these sports drinks tells us that 240 mL of the solution contains 30 mg of potassium. KH2PO4 is the only ingredient that can provide potassium. how many grams of KH2PO4 are dissolved in 240 mL of the solution? What is the molars ty of KH2PO4 in this solution? Organize abs label your calculations so that they are presented in a logical manner for full credit
