Determine the molar mass of NiCO_3 by adding the atomic masses of Ni, C, and O_3.
Calculate the number of moles of NiCO_3 using the formula: \( \text{moles} = \frac{\text{mass}}{\text{molar mass}} \).
Use the balanced chemical equation to find the mole ratio between NiCO_3 and H_2SO_4, which is 1:1.
Calculate the number of moles of H_2SO_4 needed using the mole ratio from the balanced equation.
Determine the mass of H_2SO_4 required by multiplying the number of moles of H_2SO_4 by its molar mass.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Stoichiometry
Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It involves using mole ratios derived from the coefficients of the balanced equation to determine the amount of substances consumed or produced. Understanding stoichiometry is essential for solving problems related to the quantities of reactants and products in a reaction.

Stoichiometry Concept
Molar Mass
Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a molecule. Knowing the molar mass of reactants and products is crucial for converting between grams and moles, which is necessary for stoichiometric calculations in chemical reactions.

Balanced Chemical Equation
A balanced chemical equation represents a chemical reaction with equal numbers of each type of atom on both sides of the equation. Balancing ensures the law of conservation of mass is upheld, meaning matter is neither created nor destroyed in a reaction. This balanced equation provides the necessary mole ratios for stoichiometric calculations, allowing for accurate predictions of reactant and product amounts.
