Answer :
0.805 mol 1 Rb2SO4 (3 mol ions / 1 mole 1 Rb2SO4) = 2.42 mol ions
what are moles?
A mole is merely a measuring unit. In reality, it is one of the International System of Units' seven foundation units (SI). When existing units are insufficient, new units are created. Chemical reactions frequently occur at levels where using grammes would be inappropriate, but using absolute numbers of atoms/molecules/ions would also be misleading. As a result, scientists created
A mole, like other units, must be specified or based on something repeatable. The mole's current meaning is specified, however it was formerly based on the number of atoms in a sample of the isotope carbon-12.
