Explanation:
proton number and neutron number sums up to form the mass number
The mass of 2.1 moles of the hydrate Nickel (II) carbonate pentahydrate NiCO3 x 5H2O 773.5 grams.
<h3>What are moles?</h3>
Mole is the smallest particle of atom which is equal to the Avogadro's number which is 2.303 × 10²³moles of an atom and can be calculated by,
number of moles = mass of mole / molar mass of the mole.
mass = 2.1 moles
molar mass of NiCO3 x 5H2O = 368.38
Substituting the value in the formula,
2.1 mole = mass of mole / 368.38
mass of mole = 773.59 grams.
Therefore, mass of 2.1 moles of the hydrate Nickel (II) carbonate pentahydrate NiCO3 x 5H2O 773.5 grams.
