### Chemistry Exercise: Nickel Calculations**12 (a)** Calculate the number of moles of the element present in 99.9 g of nickel.**(b)** Calculate the mass in grams of a sample containing 0.251 mole of nickel.**(c)** Calculate the number of atoms in a sample containing 0.251 mole of nickel.### Explanation:- **Moles Calculation:** Use the formula: \[ \text{Moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]- **Mass Calculation:** Multiply moles by the molar mass.- **Atoms Calculation:** Use Avogadro's number (6.022 x 10²³ atoms/mol) to find the number of atoms from moles.

Given a) Mass of Ni = 99.9 g b) No.of moles of Ni = 0.251 mol c) No.of moles of Ni =…
