There is a container containing 20g of hydrogen, caculate the number of moles of hydrogen in the container. Hence depending on using 2 or 1 as Mr of hydrogen, we get different answer of 10 or 20 moles. The thing I am confused about is that hydrogen exists as diatomic particle, ...
moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles Using Avogrado's Number Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of wat...
mass of the adhesive sheet for touch panels; the ratio of the number of moles of oxygen atoms relative to the number of moles of carbon atoms in the adhesive sheet for touch panels is 0.03-0.15; and the maximum value of the loss tangent is within the range of from -5°C to 60°C....
moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles Using Avogadro’s Number We can use Avogadro’s number to determine the number of molecules in a drop of water. Avogadro’s number tells us that there are 6.022 x 10^23 mol...
ok, I have a question, In a redox reaction, how do you calculate the number of moles of electrons transfered? Logged Bakegaku Full Member Posts: 269 Mole Snacks: +20/-5 Gender: Hydrogen peroxide is my miracle cure to everything
Here's an example: Two volumes of hydrogen gas combine with one volume of oxygen gas to form two volumes of water vapor (at least when temperatures are high enough) with nothing left over, or: 2H2 + O2 --> 2H2O Tinkering around with the implications of this law, Avogadro deduced that...
In 1909, French physicist Jean Perrin proposed Avogadro's number. He won the 1926 Nobel Prize in physics for using several methods to determine the value of the constant. However, Perrin's value was based on the number of atoms in 1 gram-molecule of atomic hydrogen. Later, the constant wa...
