How many tons of zinc can be obtained from 976 tons of zinc ore that is 78.0% zinc carbonate?

Answer : The amount of zinc obtained can be 396.9 tons.

Explanation :

First we have to calculate the amount zinc carbonate in 976 tons.

Amount of zinc carbonate =

Now we have to calculate the percentage of zinc in zinc carbonate.

As we know that,

Atomic mass of zinc = 65.38 g

Atomic mass of zinc carbonate = 125.38 g

Now we have to calculate the amount of zinc in 761.28 tons.

Amount of zinc =

Therefore, the amount of zinc obtained can be 396.9 tons.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
