Want this question answered?
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
1 mole of anything always contains 6.022*1022 things; therefore, 1 mole contains 6.022*1022 atoms.
A mole of a substance is 6.022X1023 atoms, molecules, or formula units of a substance.
one mole of a substance is described as 6.02x1023 atoms of a substance so if one mole of bromide gas contains 6.02x1023 atoms then bromide gas will contain one mole. your question is a trick question as the gas is stated as containg one mole there fore it contains one mole of bromide atoms
mole
It's a mole [mol]. A mole has 6.0221415×1023 atoms or molecules of the pure substance being measured.
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
A mole is a quantity of substance which has Avogadro's number of molecules or atoms in it.
Regardless of the substance, one mole contains the Avogadro's number of parts of the particular substance.
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
1 mole of any substance has 6.022 x 1023 atoms or molecules of that substance
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.
