Moles are carnivores that make themselves at home in lawns rich in grubs and insects. When their food is seasoned with castor oil, they will go elsewhere for meals. (Wouldn’t you?) Mix up a spray of 3 parts castor oil to 1 part dish detergent; use 4 tablespoons of this concoction in...
Chemists routinely perform calculations of the amount of substances necessary to carry out a chemical reaction. Textbooks refer to this topic as "stoichiometry." Chemists base all stoichiometric calculations on moles. A mole represents 6.022 x 10^23 for
As discussed in Raymond Chang’s introductory textbook “Chemistry,” a mole is a measure of molecules, equal to approximately 6.022x10^23 molecules, where the caret ^ refers to exponentiation. Using the ideal gas formula, you can find the number of moles of carbon dioxide (CO2) in a contai...
You'll get a detailed solution from a subject matter expert that helps you learn core concepts.See Answer Question: How do you find n (number moles of electrons transfered inbthe reaction) to use in the formula G = -nFE? How do you find n (numbe...
Tutor New to Wyzant College Senior for Math and Science Tutoring See tutors like this I'm going to assume the question states: How many moles of P4 are needed to produce 10.5 L of P4S3 at STP? First, use the ideal gas law to find moles of product produced, since the volum...
Molar mass of {eq}H_{2}O {/eq} = 18.01 g/mol There are 10.0 g hydrogen gas and 80.0 g oxygen gas available. Next, find the moles of each reactant:What is the Percent Yield? Percent Yield Equation Yield Science Lesson Summary Register to view this lesson Are you a student ...
molesofsolutevolumeofsolutionmolesofsolutevolumeofsolution You have no way of getting to the volume of solution using just a mole fraction. Strictly speaking, there is not enough information in just the mole fraction unless you are working in a very dilute solution where you can assume the densi...
For samples of solution heat treated and peak-aged states, we observe the formation of the nanocrystalline (Al,Mg)-rich oxide film and its transition to a detrimental (Zn,Cu)-rich layer from the surface to the interior. We find that the Mg content of the oxide layer decreases from 33...
