Several metals react with oxygen gas to form the metal oxide

Reference no: EM13552374

Many metals react with oxygen gas to form the metal oxide. For example, calcium reacts in the following manner. 2 Ca(s) + O2(g) 2 CaO(s)

You wish to calculate the mass of calcium oxide that can be prepared from 4.03 g Ca and 2.72 g O2.

(a) How many moles of CaO can be produced from the given mass of Ca?

(b) How many moles of CaO can be produced from the given mass of O2?
