Answer:
x= 138.24 g
Explanation:
We use the avogradro's number
6.023 x 10^23 molecules -> 1 mol C2H8
26.02 x 10^23 molecules -> x
x= (26.02 x 10^23 molecules * 1 mol C2H8 )/6.023 x 10^23 molecules
x= 4.32 mol C2H8
1 mol C2H8 -> 32 g
4.32 mol C2H8 -> x
x= (4.32 mol C2H8 * 32 g)/ 1 mol C2H8
x= 138.24 g
True. Any cosmetic containing paraffin wax, benzene, mineral oil, PEG, DEA, MEA, the suffix ethyl- or propyl-, etc. About 95% of fragrances contain petrochemicals.
Answer:
Those in lightning are charged and those in water are not charged.
Explanation:
The particles in lightning differs from those in a water in that water molecules are neutral and those of lightning are charged.
Lightning is made up of charged ions or particles that have either lost or gained electrons.
Lightning is produced as a burst or discharge of charged particles that are imbalanced withing the clouds.
Water molecules are made up of hydrogen and oxygen atoms which forms molecules held together by strong intermolecular and interatomic bonds.
Due to the sharing of electrons that has made this bonding possible, there is a net charge balance which leads to a neutrality.
Water is electrostatically neutral and not charged.
Answer:

Explanation:
Hello,
In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:

Next, using the molar fraction of argon, we compute the moles of argon:

And the moles of methane:

Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:
