5. If the reaction of carbon monoxide and oxygen gas in question 2
zheka24 [161]

Answer: The mass in grams is 514.8.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}

given molecules = 7.03\times 10^{24}  

Putting in the values we get:

\text{Number of moles}=\frac{7.03\times 10^{24}}{6.023\times 10^{23}}=11.7moles

mass of CO_2=moles\times {\text {Molar mass}}=11.7mol\times 44g/mol=514.8g

The mass in grams is 514.8.
