Answer:
2.5 moles of O₂
Explanation:
2RbNO₃⇒2RbNO₂+O₂-------------The equation is balanced
Mole ratio for the equation
2RbNO₃⇒2RbNO₂+O₂
2 2 1
RbNO₃:O
2:1---------------------------------------For every mole of oxygen produced ,two moles of RbNO₃ are required
Given
5 moles of RbNO₃ will produce ? moles of oxygen
2 moles of RbNO₃=1 mole of oxygen
5 moles of RbNO₃=?
=(5×1)/2 = 2.5 moles
