The gram atomic mass of magnesium is 24.305. Therefore, 36 g of magnesium contains (36/24.305) X Avogadro's Number or 8.9 X 1023 atoms, to the justified number of significant digits.
there are more atoms in a glass of water than grains of sand in the world
2 hydrogen atoms and one oxygen atom produces water molecules
The water molecule itself does not contain any atoms of carbon. Only two atoms of hydrogen and one atom of oxygen. However, many carbon compounds can be dissolved in water.
A water molecule (H2O) contain two hydrogen atoms.
36g water contains 12.046 x 1023 molecules.
Be, beryllium, has an atomic weight of 9g/mol. With that we can convert given grams to moles. 36g x 1mol/9g = 4 moles of Be
Approx. 4 moles.
Dissolve 36g in 100ml of water Dissolve 36g in 100ml of water -------------->lol ............ofcourse......what kind of question is this?
First work out the moles So do 36g / 80 (80 is bromine's relative atomic mass number) You have 0.45 M Then, do 0.45 * 6.02*10^23 You get 2.7*10^23, which is your answer
It is 2x6.023 x 1023
Since:- mol = mass/Mr and water has an Mr of 18 then:- 2 x 18 = 36g
36g = 1.27oz
it all depends on what element you are talking about
how many atoms are in 5.00 moles of water
The number of atoms in water depends on how many molecules of water you have. In ONE molecule of water, there are 3 atoms (2 hydrogen atoms and 1 oxygen atom).
