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.
