What Is the total atoms in CH_3(CH_2)_8COOH? Define atoms. Differentiate isobar and isotope with example. Express the relationship between number of moles, number of molecules, and Avogadro's constant. Which contains the most moles: 10.0 gg of hydrogen gas, 100 gg of carbon, or 500 gg...
The answer is that moles give us a consistent method to convert between atoms or molecules and grams. It's simply a convenient unit to use when performing calculations. You may not find it too convenient when you're first learning how to use it, but once you become familiar with it, a ...
What is a mole in chemistry definition? mole, also spelled mol, in chemistry,a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. ... In comparison, one mole of oxygen consists, by definition, of the same num...
Unit=moles h+/liter!!! We simple use conventionally unit-less number, for convenience! i.e. instead of reporting that the pH is 10E-6 moles of H/liter of soil solution we ..simple say ph=6! Common sense...not much science!!! VOTE Corey DeaneFollow Yes, Carlos it is so VOTE Ale...
A mole of aluminum is 27g, because aluminum's relative atomic mass is 27. A mole of aluminum also contains 620 billion trillion atoms. We can also use moles to talk about molecules. A mole of a compound contains 602 billion trillion molecules. A molecule of water has a relative molecular...
Mole fraction of a component in a solution describes the number of moles of the component present in the total number of moles of all the components present in the solution. x=ni∑niAnswer and Explanation: We are given: Mass of ethanol = 14.6 g ...
How many moles of water are there in 1.000 l at stp? Assume the density of water is 1000 kg/m3? An empty container has a mass of 62.000 grams. You fill it with 24.6 mL of a liquid. The final mass of the container is 81.34 grams. What is the density of the liquid to the correc...
1.71 moles NaCl ÷ 2.5 liters = 0.684 M.Calculation of Solute Needed for a Specified Molarity Consider a problem that asks for the weight of sodium sulfate, Na2SO4, required to prepare 250 milliliters (ml) of a 0.5 M solution. The first step is to calculate the number of moles of ...
A mole of substance B is the SI unit of for the amount of substance B that contains 6.023x{eq}10^23 {/eq} particles of the substance. 1 mole NaCl = 58.44 gm NaCl. Molality: The molality of any solute is the number of moles of the solute present in per kilogram of solven...
