Answer:
N(CO2) = n(CO2) x Avogadros constant
n(CO2) = mass(CO2)/Molar mass(CO2) = 112/44 = 2.5454….
N(CO2) = 2.545454… x (6.02 x 10^23) = 1.5323636 x 10^24
Therefore, the number of CO2 molecules in 112 g of CO2 = 1.53 x 10^24 molecules

that's what the role is
What Can you be more clear --Molecules change it from being less dense
Answer:
1.563 moles of SO3.
Explanation:
We begin by calculating the number of mole present in 100g of sulphur dioxide, SO2. This can be obtained as follow:
Molar mass of SO2 = 32 + (16x2) = 64g/mol
Mass of SO2 = 100g
Mole of SO2 =..?
Mole = mass/Molar mass
Mole of SO2 = 100/64
Mole of SO2 = 1.563 mole
Now, we can obtain the number of mole of sulphur trioxide, SO3 produce from the reaction as follow:
2SO2 + O2 —> 2SO3
From the balanced equation above,
2 moles of SO2 reacted to produce 2 moles of SO3.
Therefore, 1.563 moles of SO2 will also react to produce 1.563 moles of SO3.
Therefore, 1.563 moles of SO3 is obtained from the reaction.
