**stoichiometry How many hydrogen atoms are in a sample of**

31/03/2012Â Â· a) the mass of one copper atom is 64 grams divided by 6.022 x 10^23. But since you want kilograms, you should start by converting 64 grams to 0.064 kg, then dividing by N (Avogadro's number). You should get 1.063 x 10^-25 kg.... 10/12/2007Â Â· First, get moles of K. Do this by dividing atoms by Avogadro's Number: 8.970 x 10^6 divided by 6.022 x 10^23 Second, take the moles of K and multiply it by the atomic weight of K (get that from the periodic table).

**Atoms in gases MEL Chemistry VR**

After you get that answer you can use Avagadroâ€™s number, 6.022X10^23 to find the atoms. To get moles from atoms, divide number of atoms by 6.022 x 10^23. To get atoms â€¦...Question: A) Calculate the mass of a mercury atom in kg. B) How many atoms of mercury does a drop of mercury contain, knowing that the volume of a drop of mercury is $\pu{0.05mL}$ and that the density of mercury is $13.6 \times 10^3 \mathrm{kg/m^3}$

10/12/2007Â Â· First, get moles of K. Do this by dividing atoms by Avogadro's Number: 8.970 x 10^6 divided by 6.022 x 10^23 Second, take the moles of K and multiply it by the atomic weight of K (get that from the periodic table). how to get a decimal answer in mathematica 7/04/2010Â Â· Best Answer: I'll help you with these conversions and offer some advice about why you might be getting them wrong, if you don't mind. Also, I'll use the calculator's way of expressing numbers in scientific notation. So instead of writing 6.022x10^23, I'll write 6.022e23. It's just a bit simpler, and you'll know what I mean..

- 13/02/2010Â Â· From the mass of Ra 226, one can determine the number of atoms. Then one may use the definition of activity, which is: A = Î»N, where Î» is the decay constant, and N is the number of atoms.

- On the (Small) Number of Atoms in the Universe The number of atoms in the observable universe is about 10 to the 80th power (10 80). This measure is frequently used as a canonical really big number.
- Mole is a standard measurement of amount which is used to measure the number atoms (or) molecules. 1 mole of something is equal to 6.0221415x10 23 of it. This online unit converter will help you to convert the grams of a molecule to the number of moles based on the weight of â€¦
