Answer:
<h2>14.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.05 moles</h3>
Hope this helps you
Answer:
268.75 K
Explanation:
We are given;
- Initial pressure, P1 as 600 torr
- Initial temperature, T1 as 215 K
- New pressure, P2 as 750 torr
We are required to determine the new temperature, T2.
To solve this question we are going to use the pressure law of gases.
According to pressure law, the temperature of a fixed mass of a gas and its pressure are directly proportional at constant volume.
That is;
Pα T
Therefore;
Thus,
Therefore, the new temperature is 268.75 K
1,2,3, or 4. Generally, carbon likes to make 4 bonds to 4 different atoms. For example, in methane(CH4), Carbon makes 4 bonds to 4 hydrogens. However, Carbon can also make double and triple bonds to atoms. This means that of the 4 bonds, more are used to bond to one thing. For example, in the compound CN, Carbon bonds to hydrogen on one side and triple bonds to Nitrogen on the other. This shows carbon can bond to at 2 atoms as well as 4 at a time. using a one double bond carbon would only bond to 3 atoms. I cant think of an example where carbon only bonds to one other atom without breaking the octet rule, but all the other values can be validated through examples. So, I still think the bottom answer is correct. Hope this helped!
