Is 101 a prime number? - Socratic
Apr 7, 2016 · Yes, it has no positive factors apart from 1 and 101. To test if 101 is prime, check for divisibility by each of the primes 2, 3, 5 and 7. There is no need to check beyond these as 11^2 = 121 > 101. So if 101 was divisible by some number less than 101 then it would be divisible by a number less than 11. 101 is not divisible by 2 since it ends with an odd digit. 101 is not …
What are the units used for the ideal gas law? - Socratic
Dec 25, 2013 · The equation for the Ideal Gas Law is: PV = nRT On the whole, this is an easy equation to remember and use. The problems lie almost entirely in the units. SI units Pressure, P Pressure is measured in pascals ("Pa") — sometimes expressed as newtons per square metre ("N·m"^"-2"). These mean exactly the same thing. Be careful if you are given pressures in …
Stoichiometry - Chemistry - Socratic
Stoichiometry is the chemistry that mathematically relates all substances in a reaction, quantitatively relating the amount of reactants and products in a chemical reaction. It allows the chemist to determine the amount of product that will form from a given amount of reactants, or the amount of one reactant that is needed to react completely with some specific amount of the …
How do you solve a gas law stoichiometry problem? | Socratic
Jan 3, 2014 · The easiest way is to remember that in order to use stoichiometry, you need to know the moles of the two substances concerned. > We can use the gas laws to help us to determine the effect of temperature, pressure, and volume on the number of moles of a gas. The central requirement of any stoichiometry problem is to convert moles of "A" to moles of "B". If …

How can I calculate wavelength of a photon? + Example - Socratic
Apr 25, 2015 · If you know the frequency of the photon, you can calculate the wavelength using the equation lambda=c/nu where c is the speed of light and nu is the frequency. Example: for a photon of frequency 6times10^(12) s^(-1) the wavelength is lambda=(3times10^8 m/s)/(6times10^(12) s^(-1))=5times10^(-5) m=50 micrometers
