The average atomic mass of chromium to 3 decimal points is 52. 055 g. mol.
<h3>What is the average atomic mass?</h3>
"The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight."
Given the different isotopes of chromium.
The four isotopes of chromium are cr-50, cr-52, cr-53 cr-54.
The average atomic mass will be
Let us take the weighted average of your isotopes:
50 × 0.0434 + 52 × 0.8379 + 53 × 0.095 + 54 × 0.0237 = 52. 055 g.
Thus, the average atomic mass of chromium is 52. 055 g.

Answer: a) No, both are different.
b) Ramesh- 9.9%
Sarika - 10%
Explanation:
According to the solution prepared by Ramesh,
Mass of sugar he took (Solute) = 10 g
Mass of water he took (Solvent) = 100 g
Thus Mass % of the solution =
According to the solution prepared by Sarika,
Mass of sugar she took (Solute) = 10 g
Mass of Solution she took = 100 g
Thus Mass % of the solution =
Explanation:
Answer:
D.
Explanation:
Nuclear energy does not have greenhouse gas emissions. The emissions produced by nuclear fission plants are similar to renewable energy sources.The generation of power using nuclear energy does not affect air quality thus providing a clean source of energy.Nuclear energy originates from radioactive material which are harmful to living organisms.
This is a benefit I’m not sure if a negative
This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well.
Answer:
The answer is 3.87 J/g°C
Explanation:
Here is the equation we are going to use:
C= specfic heat in J/g°C
q = heat in joules (J)
m = mass in grams (g)
T = change in temperature
Here is what is given:
q = 849 J
m = 95.4 g
T = 48.0 - 25.0 = 23°C
Find:
Specific heat capacity in J/g
The first thing we are going to do is plug everything into the equation:
Then we are going to solve for C
Hope this helps!
