How many grams of sodium would be needed to produce 1.00kg of sodium hydroxide?
Answer:
575 g
Explanation:
1 kg of sodium hydroxide is 1000/40=25 mol.
So 25 mol of sodium will be needed.
25 mol of sodium is 575 g.
According to the stoichiometry of the given chemical equation, 575 g s of sodium would be needed to produce 1.00 kg of sodium hydroxide.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
46 g sodium gives 80 g sodium hydroxide, thus 1000 g sodium hydroxide requires 46×1000/80=575 g sodium.
Thus, 575 g s of sodium would be needed to produce 1.00 kg of sodium hydroxide.
