How many grams are in 2.40 moles of sodium hydroxide (NaOH)?
Bogdan [553]

Answer:

96g

Explanation:

Given parameters:

Number of moles of NaOH = 2.4moles

Unknown:

Mass of NaOH = ?

Solution:

The mass of a substance given the number of moles can be found using the expression below;

     Mass of NaOH  = Number of moles x molar mass;

  Molar mass of NaOH  = 23 + 16 + 1 = 40g/mol

Now input the parameters and solve;

    Mass of NaOH  = 2.4 x 40  = 96g

Sometimes you are given a measured amount of two or more reactants and asked how much product can be formed. Explain what steps
Westkost [7]

Explanation:

To solve this problem, follow these steps;

  • Obtain a balanced equation of the reaction and familiarize with the reactants and products.
  • Find the number of moles of the reacting species since they are the known matter in terms of quantity.
  • From the number of moles, determine the limiting reactant.
  • The limiting reactant is the one given in short supply.
  • Such reactant determines the extent of the reaction.
  • Compare the moles of this specie to that of the products using the balanced equation.
  • Obtain the mole of the desired product and find the mass or desired quantity.
  • simply work from the known specie to the unknown
