it all depends on what element you are talking about

1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
Molar mass of magnesium is 24gmol-1. mass of 1.5 mg mole 36g.
36g water contains 12.046 x 1023 molecules.
36g = 1.27oz
1 mole O = 15.9994g 36g O x 1mol O/15.9994g O = 2.3 moles O
Fresh Pair is an online store that sells a wide selection of bras including the 36g size. They sell 175 bras in the 36g size range. Bare Necessities also sells 36g bras. They have around 250 different 36g bra options.
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
36 g of water (in any state) is 2 gram moles of water. At STP a mole of any gas has a volume of 22.4 litres, so two moles is 44.8 litres. This value would have to be corrected to the pressure and temperature of the actual conditions.
