1000 to the power 4 not so good at math but
Litmus paper maybe? There are a bunch of things you can use for this, but high school chem teachers love their litmus paper
As we know that there are avogadro no. of atoms in 9 g of beryllium.
1 mole of beryllium = 6.02 * 10^23 atoms
so 2.5 mole= 6.02*10^23*2.5 i.e = <span>15.055 × 10^23 atoms </span>
This is what I got hope this makes sense:There is 1 mol of Mg 2+ ions in one mole of MgCl2, we can get that from the formula.
Multiply 3.00 moles by 6.022x10^23 to get moles of MgCl2.
There are 6.022x10^23 ions in one mole of substance.
(3.00)(6.022x10^23)
=1.81x10^24 Mg 2+ ions
Hope it helps though
Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass
Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population,
mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy
