Answer:
This question is incomplete
Explanation:
Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.
Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.
This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.
An example of a standard curve is provided in the attachment for guidance.
The Tassie Devil has held this title for over 80 years. Prior to 1936, the largest carnivorous marsupial in the world was the thylacline, which is commonly know as the Tasmanian Tiger. The thylacline is a distant relative of the Tasmanian Devil and was over the twice it’s size!
A mother gives birth to around 20-40 Joeys at once. However, these joeys have to race to her pouch, which only has 4 teats. Talk about a hard start to life!

The four main stages of Interphase are Gap 0, Gap 1, S phase and Gap 2. Interphase appears to be a resting stage in cell divisions but actually many activities or processes happens at this phase. Interphase generally lasts at least 12 to 24 hours in mammalian tissue.
