Answer:
96%
Explanation:
To find the percent yield, we can use this equation
The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.
Thus the percent yield is 96%

Answer:
Order of increasing strength of intermolecular attraction:
>
>
> Ar
Explanation:
can form hydrogen bond as H atom is attached with electronegative atom O.
Rest three, ,
, Ar are non-polar molecules.
In non-polar molecules, van der Waal's intermolecular forces of attractions exist. Hydrogen bonding is stronger intermolecular attraction then van der Waal's intermolecular forces of attraction, hence, has strongest intermolecular attractions.
Ar will have least intermolecular attraction, as it behaves almost as ideal gas and there is no intermolecular attraction exist between molecules of ideal gases.
Molecular size and mass of is high as compared to
.
van der Waals intermolecular forces of attraction increases with increase in size.
Therefore,
Order of increasing strength of intermolecular attraction will be:
>
>
> Ar
Answer:
Explanation:
<u>1. Energy to heat the liquid water from 55ºC to 100ºC</u>
- m = 10.1g
- C = 4.18g/JºC
- ΔT = 100ºC - 55ºC = 45ºC
<u>2. Energy to change the liquid to steam at 100ºC</u>
- λ = 40.6kJ/mol
- n = 10.1g / 18.015g/mol = 0.5606mol
<u>3. Total energy</u>
- Density=2.35g/mL
- Mass=33.67g
