The sum of the mass numbers and the sum of the atomic numbers balance on either side of an equation
Clearly volume will INCREASE almost sevenfold, as we would expect if we reduce the pressure. ... Assuming this is an ideal gas, and that the number of molecules *n* of this gas remains constant, and given that the temperature is also ... That is, in these conditions, pressure times volume is constant :
Answer:
3.25×10²⁴ molecules.
Explanation:
From the question given above, the following data were obtained:
Number of mole of CO₂ = 5.4 moles
Number of molecules of CO₂ =?
The number of molecules of CO₂ in 5.4 moles can be obtained as follow:
From Avogadro's hypothesis,
1 mole of CO₂ = 6.02×10²³ molecules
Therefore,
5.4 moles of CO₂ = 5.4 × 6.02×10²³
5.4 moles of CO₂ = 3.25×10²⁴ molecules
Thus, 5.4 moles of CO₂ contains 3.25×10²⁴ molecules.
