Question

what is the answer of this question plz help me

Answer 1

To solve this question , I'll apply law of conservation of mass. According to the law mass of the reactants must be equal to mass of the product. Hence as given , the total mass of the reactants must be 3×10^3 (2.00×10^3 + 1.0×10^3) which will be equal to the mass of the product.
Hence the mass of NH3 formed is 3×10^3g.
