Answer:
1520mmHg
Explanation:
Data obtained from the question include:
V1 (initial volume) = 600 mL
P1 (initial pressure) = 760 mmHg
V2 (final volume) = 300 mL
P2 (final pressure) =.?
Using the Boyle's law equation P1V1 = P2V2, the final pressure of the gas can easily be obtained as shown below:
P1V1 = P2V2
760 x 600 = P2 x 300
Divide both side by 300
P2 = (760 x 600) /300
P2 = 1520mmHg
The final pressure of the gas is 1520mmHg
Answer:
Set an alarm for five hours after your bedtime.

When the alarm goes off, stay up for 30 minutes. Enjoy a quiet activity like reading.
Fall back asleep.
Explanation:
1mol aluminium chloride gives 1mol aluminium and 3mol chloride
density equals mass divided by volume
d=m/v
m=v*d
=78.3*2.7
=211.41grams
