Answer:
False
Explanation:
According to kinetic molecular theory, all collisions are perfectly elastic and energy is conserved.
Answer:
Approximately 53.3 %.
Explanation:
Molar mass of C2H4O2
= 2 * 12.011 + 4 * 1.008 + 2 * 15.999
= 60.052
% oxygen = (31.998* 100) / 60.052 = 53.28 %
Answer:
The Great Compromise settled matters of representation in the federal government. The Three-Fifths Compromise settled matters of representation when it came to the enslaved population of southern states and the importation of enslaved Africans.
Explanation:
Answer: A) 4.2 x 10^20
Explanation:
All of the answers are pretty much the same so it comes down to significant digits.
You always go with the <u>least number of significant digits</u> that you have been given.
So 0.24g only has 2 so our answer will only have 2 significant digits.
If you want to know how to do the math here it is:
Avogadro's Number: 6.022 x 10^23
This number also equals 1 mole.
1 mole of sucrose is equal to 342.3g.
So the equation is set up like this:
0.24g x 1 mol / 342.3 g x 6.022 x 10^23 / 1 mol = 4.2 x 10^20 molecules.
Answer:
<h2>0.66 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
We have
We have the final answer as
<h3>0.66 moles</h3>
Hope this helps you
