Answer:
The concentration of the copper(II) sulfate solution is 0.99 M
Explanation:
Step 1: Data given
Mass of copper(II) sulfate = 79 grams
Volume of the flask = 500 mL
Molar mass copper(II) sulfate = 159.61 g/mol
Step 2: Calculate moles copper(II) sulfate
Moles CuSO4 = Mass CuSO4 / molar mass CuSO4
Moles CuSO4 = 79.0 grams / 159.61 g/mol
Moles CuSO4 = 0.495 moles
Step 3: Calculate concentration
Concentration CuSO4 = moles / volume
Concentration CuSO4 = 0.495 moles / 0.5 L
Concentration = 0.99 M
The concentration of the copper(II) sulfate solution is 0.99 M
Answer:
<u>Who: </u>Svante Arrhenius.
When: Claimed in 1896 that fossil fuels has a negative effect on our atmosphere.
<u>How:</u> Svante Arrhenius proved that fossil fuels had a negative effect by calculating the output of buildings that emit fossil fuels, and lead to the conclusion by his calculations that the industry might one day bring global warming. Svante Arrhenius' theory of electrolytic dissociation and his model of the greenhouse effect also helped him to prove that his remarks about fossil fuels and global warming is true.
<u>Where:</u>
I cannot find any source that mentions the where. What do you mean by where?
I hope my other information help you. I apologies to only be able to answer partially.
Star is rats backwards if that helps
