Question

How many moles of Oxygen are in 1.6 mol of Ca(NO3)2?

Answer 1

Therefore, each mole of calcium nitrate has six moles of oxygen. 

Simply multiply your given moles by six.

Answer 2

Answer : The moles of oxygen are, 9.6 moles.

Explanation : Given,

Moles of $Ca(NO_3)_2$ = 1.6 mole

As we know that,

In $Ca(NO_3)_2$, there are 2 atoms of nitrogen, 1 atom of calcium and 6 atom of oxygen.

Now we have to calculate the moles of oxygen.

As, 1 mole of $Ca(NO_3)_2$ contains 6 moles of oxygen.

So, 1.6 moles of $Ca(NO_3)_2$ contains $1.6\times 6=9.6$ moles of oxygen.

Therefore, the moles of oxygen are, 9.6 moles.
