The answer would be, B, Nuclear energy stored in the oceans has a major effect on Earth's weather and climate
First we need to calculate the molar mass of
:
Na: 22.99g * 2 = 45.98g
Cr: 51.996g
O: 15.999g * 4 = 63.996g
Then add all of them together:
Now we know the molar mass of
is 161.97g.
We are given the amount of grams used in the solution. So let's find how many moles that were used:
We are asked to calculate the molarity, and we know the molarity formula is as follows:
We just calculated the number of moles that were used, and we are given the amount of solution (in mL, but we can convert 630 mL to 0.63 L by dividing by 1000 since there are 1000 mL in 1 L). So let's plug in the values to calculate for molarity:
So now we know that
the molarity of the solution is 0.12 M.
The answer is the most probable location of electrons in an atom
Google says it is 9.01218, idk if that helps
