Answer:
Explanation:
a) m-Xylene
It is an aromatic hydrocarbon having molecular formula, C8H10. in this compound, two methyl groups are present at 1 and 3 positions of benzene ring.
b) o-Cresol
It is an organic compound having molecular formula, C7H8O. It is a substituted phenol in which a methyl group is present at ortho position.
c) 3-Bromo-4-nitrobenzenesulfonic acid
In this aromatic compound, three functional groups: -SO3H, -NO2 and -Br are present on the benzene ring at 1, 4 and 3 postion respectively.
Mass of CO₂ = 132 g
<h3>Further explanation </h3>A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mole also can be formulated :
moles of CO₂ = 3
mass of CO₂(MW=44.01 g/mol) :
Density is mass divided by volume. Therefore, volume is mass divided by density.
