Copper is a product of the reaction that occurs when dry ammonia is passed over a sample of heated copper(II) oxide. The equatio

n for the reaction is given below. 2NH3 + 3CuO --> 3Cu + 3H2O + N2 Calculate the mass of copper produced if 0.12 dm^3 of nitrogen is produced at room temperature and pressure (rtp). (Relative atomic mass of Cu = 64; One mole of gas occupies 24 dm3 at rtp​

Answer:

0.12 dm^3 x (1 mol/24 dm^3) = ? mols N2

mols Cu = ? mols N2 x (3 mols Cu/1 mol N2) = ?

Then g Cu = mols Cu x atomic mass Cu = ?

3. A 0.025L solution of HCl is neutralized by 0.018L of a 1.0 M NaOH solution. What is the concentration of the HCl solution?​
Nookie1986 [14]

The concentration of the HCl solution is 0.72 M.

<h3>How do we calculate the concentration?</h3>

Concentration of the required solution by the use of the known concentration solution will be determine by using the below equation as:

M₁V₁ = M₂V₂, where

  • M₁ & V₁ are the molarity and volume of the HCl solution.
  • M₂ & V₂ are the molarity and volume of the NaOH solution.

On putting values in the above equation, we get

M₁ = (1)(0.018) / (0.025) = 0.72 M

Hence required concentration of HCl is 0.72M.
