To find the number of moles of water present in 180 g of water, we can follow these steps:1. Identify the formula for calculating moles: The number of moles (n) can be calculated using the formula: \( n = \frac{\text{G
use the ideal gas constant to calculate the number of moles of water vapor. p=18.65 torr v=39.5 L r=0.08206 t=294 K this is the equation im supposed to use right? n= PV/RT This is what i got. n=(18.65)(39.5)/(0.08206)(294)=30.5 mol H20 but when i look it up online the ...
Explain how to calculate each of the following: a. The number of moles of water formed during the experiment b. the value of the molar enthalpy of neutralization Δ Hneut, for the reaction between HCl(aq)andNaOH(aq) Molar Enthalpy (Neutralization):...
Moles are the number of atoms or molecules needed to produce a sample in which the number of grams equals the number of atomic mass units found in a single atom or molecule. This number is {eq}6.022 \times 10^{23} {/eq} and is called Avogadro's number....
molecules in a drop of water = (6.022 x 1023molecules/mole) x 0.002275 moles molecules in a drop of water = 1.67 x 1021water molecules Put another way, there are1.67 sextillion water molecules in a water drop. Now, the number of atoms in a droplet of water is 3x the number of molecu...
Number of moles in 180 g of water = 180/(18)=10The number of moles in 180 g of water is...
molecules in a water drop = (6.022 x 102^3 molecules/mole) x 0.002275 moles molecules in a water drop = 1.67 x 10^21 molecules of water. In another way; there are 1.67 sextillion water molecules in a water droplet. Now, the number of atoms in one drop of water is 3x the number ...
(ii) Calculate the value of x in the formula of the hydrated potassium carbonate, K2COxH2O.Show your working.X =[2](c)One of the errors associated with this method is caused by the solubility of carbon dioxide in water.Suggest two modifications which could reduce this error.modification 1...
moles of water = molecules of water / Avogadro's number moles of water = 3.35 x 1022/ 6.02 x 1023 moles of water = 0.556 x 10-1or 0.056 moles in 1 gram of water
Fun Facts of Measurement & Math Theconceptof the mole helps to put quantitative information about what happens in achemical equationon a macroscopic level. For example, in thechemical reaction2H2O → O2+ 2H2, two moles ofwaterare decomposed into two moles of molecularhydrogenand one mole of ...
