Question

For the reaction, calculate how many moles of the product form when 0.016mol of O2 completely reacts.
Assume that there is more than enough of the other reactant.
2Ca(s)+O2(g)→2CaO(s)

Answer 1

use the coefficients from the balanced reaction, because that is what makes the \(mole\) ratio

Answer 2

Multiply the number of moles of O2 by 2.
0.016*2
