The empirical formula for any compound can be determined in a few easy steps. The procedure involves finding the amount of each element in the compound and converting that amount to moles, followed by individual mole ratio calculations. Once the individual mole ratios are calculated, the ratios c...
Probability is all about how likely is an event to happen. For a random experiment with sample space S, the probability of happening of an event A is calculated by the probability formula n(A)/n(S).
According to the empirical rule, if the data form a "bell-shaped curve" (normal distribution), approximately what percent of the observations will be contained within +/- 2 standard deviations from the arithmetic mean? According to the empirica...

Though the researchers have no plans themselves to turn their formula into some sort of widely accessible calculator, they’re open to existing student loan repayment calculators adopting their model so that I can help as many borrowers as possible. ...
The cooling behavior of a solvent is a function of the number of moles of added solute. Primary Learning Outcomes At the end of this lesson, students will be able to: • Be familiarized with data collection using the Vernier LabPro and TI calculator ...
When you have the empirical formula of a chemical compound and you need to find the molecular formula of that same chemical compound, you can find the scaling factor you need by dividing the molar mass of the compound by the molar mass of the empirical formula. For example, you might nee...
In the binomial probability distribution, let the number of trials be n = 4, and let the probability of success be p = 0.4471. Use a calculator to compute the following. (a) The probability of three successes. (Round your...
