Mixtures are unlike chemical compounds, because: The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation. ... When mixed, individual substances keep their properties in a mixture, while if they form a compound their properties can change.
Answer:
33.8 g Solution
Explanation:
A chemistry student needs 15.0 g of methanol for an experiment. The concentration of ethanol in the solution is 44.4% w/w, that is, there are 44.4 g of methanol every 100 g of solution. The mass of solution that would contain 15.0 g of methanol is:
15.0 g Methanol × 100 g Solution/44.4 g Methanol = 33.8 g Solution
Since 33.8 g are required and 320. g are available, there is enough solution for the requirements.
The concentration of copper in the solution is
The volume of the solution = 1.00 L
Overall balanced equation of reaction is,
Mole ratio for,
Remained moles of en are= (0.00120-0.000500)
The concentration of copper in the solution is,
Therefore, the concentration of copper in the solution is
