Answer: 159.61 g/mol
Copper has a molar mass of 63.546 g/mol
Sulfur has a molar mass of 32.065 g/mol
Oxygen has a molar mass of 16 g/mol, multiply by 4 and it is 16 x 4 = 64 g/mol
63.546 + 32.065 + 64 = 159.61 g/mol
Answer:
Explanation:
We have the number . Standard notation would basically be this number without the part.
To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).
So, when we move the decimal point 6 places to the left, the resulting number is: , with 5 zeros after the decimal point before a nonzero number.
Thus, the answer is .
C. protons and neutrons combined
<u>Answer:</u>
<em>The final volume must be 400 mL.</em>
<em></em>
<u>Explanation:</u>
Let us assume the Initial volume as 100ml
Using dilution factor formula
So,
Thus, the final volume must be 400 mL.
Answer:
The answer is molarity.
Explanation:
I just took the test but you have to remember that the concentration of solutes in a solution is expressed as M which equals moles of solute/liters of solution. This is the definition of molarity.
I hope I helped! :D
