Answer:
The answer to your question is below
Explanation:
An atom with four electrons in its valence shell is capable of forming:
single bonds and atom with the described characteristics, can form 4 single bonds or a combination of single bonds and double or triple bonds. Ex alkanes
double bonds this atom can form one double bond and two single bonds or two double bonds. Ex alkenes
triple bonds this atom can form one triple bond and one single bond, Ex alkynes.
Moles = mass/atomic weight of mercury
= 98.3/200.59
= 0.49 moles.
Number of atoms = moles x 6.02 x 10^23
= 0.49 x 6.02 x 10^23
= 2.94 x 10^23 atoms.
Hope this helps!
Answer:

Explanation:
First of all, we need to convert the pressure of the gas from torr to Pa. We know that:
1 torr = 133.3 Pa
So, the pressure in Pascals is

Then we also have:
n = 0.133 number of moles of the gas
volume of the gas
The ideal gas equation states that

where R is the gas constant and T the absolute temperature. Solving the equation for T, we find

In Celsius, it becomes
