The answer is 9.
First convert 40 cm into metres.
40cm/100= 0.4 metres
0.4 times 9 = 3.6
PV=nRT
P= ? atm
V= 2 L
T= 423 K
n= 2.3 moles
R= 0.08205
(P)(2)=(2.3)(0.08205)(423)
P= (79.826445)/(2)
P= 39.9132225 atm
Answer:
Solid metals are good conductors of heat and electricity
Explanation:
The square of the orbital period of mercury is 7744
<h3>How to determine the square of the orbital period?</h3>
The square of a value (x) is calculated by:
Square = x²
The orbital period of mercury is:
orbital = 88 days
So, the square is:
Mercury = 88²
Evaluate
Mercury = 7744
Using the same formula for the other satelite objects, we have:
- Venus = 225² = 50625
- Earth = 365² = 133225
- Mars = 687² = 471969
- Jupiter = (12 years)² = 144 years²
- Saturn = (29 years)² = 841 years²
- Uranus = (84 years)² = 7056 years²
- Neptune = (165 years)² = 27225 years²
When the unit is not stated, the orbital period is in days
