Considering the definition of STP conditions, 0.02455 moles are contained in 550 mL of carbon dioxide at STP.

Definition of STP condition

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Amount of moles contained in 550 mL

In this case, you can apply the following rule of three: if by definition of STP conditions 22.4 liters are occupied by 1 mole of helium, 0.550 L (0.550 L= 550 mL, being 1 L= 1000 mL) are occupied by how many moles?

[tex]amount of moles=\frac{0.550 Lx 1 mole}{22.4 L}[/tex]

amount of moles= 0.02455 moles

Finally, 0.02455 moles are contained in 550 mL of carbon dioxide at STP.
