<u>Given :</u>
Mass of niobium (Nb) = 237 g
<u>To determine:</u>
The Number of moles of niobium in the given mass
<u>Explanation:</u>
In chemistry, moles (n) is a unit of measurement which is given by the ratio of the mass of the substance (m) to its atomic or molar mass (M)
i.e. n = 'm' in grams/ 'M' in grams.mole⁻¹
The atomic mass of Nb = 94 g/mol
Thus,
n = 237 g/ 94 g.mol⁻¹ = 2.521 moles
Ans: Number of moles of Nb rounded off to the nearest tenth is 2.5 moles
Explanation:
An ionic solution is a solution that has anions and cations. This is formed when ionic compounds dissociate in water. The ionic solution can be used as a battery because their respective ions can be attracted to either node of a battery. The cathode (+) attracts anions (negatively charged ions) and the anode (-) attracted cations (positively-charged ions). The reaction between the nodes and the respective ions in the solution causes electrons do be either donated or received. This ensures that the ionic solution (electrolyte) acts as channels for transport of electrons across the nodes to complete a circuit.
