The molecular weight of a substance is calculated by adding the molecular mass of each element present in the molecule multiplied by the number of times each element is in the molecule. For greater clarity, we can organize a table that allows us to do the calculations. We have the following structure for water:
The molecular weight of water will be:
2.01568 + 15.999 = 18.0468=18.0 g/mol
Answer= 18.0
The answer is B. Because reactions are what goes in. Products are what comes out
Answer:
9. Electron Affinity
10. The second option....
The number of mole of copper in the sample is 0.008 mole.
Mole is simply defined as the unit of amount in a substance.
The mole of a substance can be obtained by dividing the mass of the subtance by its molar mass i.e
Mole = mass / molar mass
With the above information, we can obtain the mole of copper in the compound as follow:
Mass of copper = 0.5066 g
Molar mass of copper = 63.5 g/mol
<h3>Mole of copper =? </h3>
Mole = mass / molar mass
Mole of copper = 0.5066 / 63.5
<h3>Mole of copper = 0.008 mole </h3>
Therefore, 0.008 mole of copper was initially present in the compound.
