If the empirical formula for a compound is NO2 and the molecular mass is 230.05 g/mol, what is the molecular formula for the com
PilotLPTM [1.2K]

Answer: \text{N}_{5}\text{O}_{10}

Explanation:

  • The atomic mass of nitrogen is 14.0067 g/mol.
  • The atomic mass of oxygen is 15.9994 g/mol.

This means the molecular mass of nitrogen dioxide is 14.0067+2(15.9994)=46.0055 g/mol.

Dividing this molecular mass of the compound we need to find, we get that

\frac{230.05}{46.0055} \approx 5.

So, the final answer is \boxed{\text{N}_{5}\text{O}_{10}}

How many moles of CO2 are produced when 2.5 moles of O2 react according to the following equation?
alexdok [17]

Answer:

1.5 moles of CO₂ are produced

Explanation:

Based on the chemical equation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O<em> -The reaction of the question is wrong-</em>

5 moles of oxygen reacts per mole of propane, C₃H₈, to produce 3 moles of CO₂ and 4 moles of water.

If 2.5 moles of oxygen react and, 5 moles of oxygen produce 3 moles of CO₂, moles of CO₂ produced are:

2.5 moles O₂ * (3 moles CO₂ / 5 moles O₂) =
