Note the molecular mass of a copper(I) oxide molecule in the image below. What is the mass of 8.250 moles of Cu2O?
xz_007 [3.2K]

Answer : The mass of copper(I) oxide is, 1180.5 grams.

Explanation : Given,

Moles of copper(I) oxide = 8.250 mol

Molar mass of copper(I) oxide = 143.09 g/mol

Formula used:

\text{ Mass of copper(I) oxide}=\text{ Moles of copper(I) oxide}\times \text{ Molar mass of copper(I) oxide}

Now put all the given values in this formula, we get:

\text{ Mass of copper(I) oxide}=(8.250moles)\times (143.09g/mole)=1180.5g

Therefore, the mass of copper(I) oxide is, 1180.5 grams.

The picture on the left represents the reactants in the equation and the picture on the right represents the products. Does this
JulijaS [17]
According to Law of conservation of matter," matter can neither be created nor destroyed but is conserved and remains constant over time'.

In above picture let suppose the Blue balls represent N₂ molecule and White balls represent H₂ molecules.

So, left picture represent reactants,

                                    2 N₂  +  6 H₂

And , right picture represent products,

                                     4 NH₃

So, there are 4 N atoms and 12 Hydrogen atoms in reactants and 4 N atom and 12 Hydrogen atoms in products. Means the mass of elements is conserved. The overall reactions is as follow,


                                    2 N₂  +  6 H₂   →   4 NH₃

Result:
          Yes! This reaction follow Law of conservation of Matter.
