Question

How many molecules of CO are produced when 2.73 moles of HPO3 react? 4HPO3 + 12C ----> 2H2 + 12CO + P4

Answer 1

To determine the number of molecules of CO produced from 2.73 moles of HPO3, we need to use the balanced equation and mole ratios.

Step-by-step explanation:

To determine the number of molecules of CO produced from 2.73 moles of HPO₃, we need to use the balanced equation and mole ratios. From the given equation:

4HPO₃ + 12C → 2H₂ + 12CO + P4

It can be seen that the mole ratio between HPO₃ and CO is 12:12. Therefore, for every 12 moles of HPO₃, 12 moles of CO are produced.

Since we have 2.73 moles of HPO3, we can use proportion to find the number of moles of CO:

(2.73 mol HPO₃ / 12 mol HPO₃) x 12 mol CO = 2.73 mol CO

Therefore, 2.73 moles of HPO₃ will produce 2.73 moles of CO.

Answer 2

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 =
`((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
