How many molecules of CO are produced when 2.73 moles of HPO3 react? 4HPO3 + 12C ----> 2H2 + 12CO + P4
Zina [86]
According to the balanced chemical equation:
4 HPO₃ + 12 C → 2 H₂ + 12 CO + P₄
4 moles of HPO₃       ---gives---> 12 moles of CO
2.73 moles of HPO₃  ---gives---> ? moles of CO
so number of moles of CO = \frac{(2.73 * 12)}{4} = 8.19 moles of CO
Number of molecules of CO = number of moles * Avogadro's number
                                       = 8.19 * (6.022 * 10²³) = 4.93 * 10²⁴ molecules
