Answer:
3.54 mol
Explanation:
When at STP (Pressure of 1 atm & T of 273.16 K), one mol of any given gas occupies 22.4 liters.
With the above information in mind we can calculate the number of moles, using the factor 22.4 L/mol:
79.2 L ÷ 22.4 L/mol = 3.54 mol
There are 3.54 moles of the gas present in the container.

2. How many electrons are in Lithium's outer shell?
3. How many times can Oxygen bond?
4. What is the charge on a phosphorus ion?

Answer:
jwwnwwjkqnwjwmwnqnqwnmqaj
Answer:
1. 8
2.1
3.4 times
4.3-
5. 2+
Explanation:
1. it qualifies under the octet rule and is completely stable.
2. 1 because it fills every shell and has one left over
3. each time an element like oxygen bonds it can be surrounded by 8 electrons in order to be stable and each line that you may see counts as two electrons so it can have 1 bond line in each direction.
4.&5. It just is that way
An object accelerates at 8 m/s2 when a force of 40 N is applied to it. What is the mass of the object
Answer:
f=ma
40=m*8
m=5kg
another object of same mass is added
=>m=5+5=10kg
f=10*8=80N
