In order to make 100 mL of a 17% sodium azide solution, you would need to weigh out 17 grams of sodium azide and then add water until the final volume is 100 mL. You can make use of this equation in another way. Say you're told that the solution you will be using has 45 grams...
This means that in 10 mL of a 1 M NiSO4 solution there are 10 mmol of NiSO4. When trying to calculate mmol of a substance always remember to set the problem so that you can cross out all the units until you are only left with the unit you want. That way you know you did the ...
Example 2:Calculate the volume of an elliptic cylinder whose base radii are 7 inches and 10 inches, and whose height is 15 inches. Use π = 22/7. Solution: The base radii of the given elliptic cylinder are, a = 7 inches and b = 10 inches. ...
Learn what inventory costs retailers need to keep track of, how to calculate total inventory costs, and how to reduce them.
Solution: “default sample size” The analyst says: split run (A/B test) with 5,000 observations each and a one-sided test with a reliability of .95. Out of habit. What happens here? What happens when drawing two samples to estimate the difference between the two, with a one-sided te...
Now we need to calculate the marginal revenue for the Elens Group of companies based on the provided data. Given, Solution: We can calculate Marginal Revenue by using the below formula Marginal Revenue (MR)= Change in Revenue / Change in Quantity ...
If a solution contains 0.10 g NaCl in 1.0 ml of solution, what is the molarity? Molar mass of NaCl = 58 g / mole Converting 0.1o g NaCl to moles, we have 0.1o g / 58 g/mol = 0.0017 moles Converting 1.0 ml of solution to liters (L) we have 1.0 ml /1000 ml/L =...

Example: Phil weighs 155 pounds. To calculate the volume of his body, divide by the average density of the human body in pounds per gallon: 155pounds1gallon8.3pounds=18.41gallons=2.43cubic feet=0.07cubic meters References Phil Plait's Bad Astronomy: Floating in Water ...
Learning how to calculate molarity isn't difficult; the key is to remember the units of molarity (M): moles per liter. Find the molarity by calculating the number of moles of the solute dissolved in liters of a solution. Molarity is a unit of concentration, measuring the number of moles...
