A sailor on a trans-Pacific solo voyage notices one day that if he puts 714. mL of fresh water into a plastic cup weighing 25.0 g, the cup floats in the seawater around his boat with the fresh water inside the cup at exactly the same level as the seawater outside the cup (see sketch at right). fresh water salt water Calculate the amount of salt dissolved in each liter of seawater. Be sure your answer has a unit symbol, if needed, and round it to 2 significant digits. You'll need to know that the density of fresh water at the temperature of the sea around the sailor is 0.999 g/cm. You'll also want to remember Archimedes' Principle, that objects float when they displace a mass of water equal to their own mass. olo

Assume that a growth curve was done at a less-than-optimal salt concentration. Predict how the growth curve would change at a more optimal salt concentration. Explain your thinking.

Assuming that the standard solution contains 20.0 g/L of Red Dye #40, report the concentration in g/L of Red Dye #40 in your unknown. The path length is 1.00cm To test the unknown and standard solution, 0.1 mL of the unknown was dispensed into a 50-mL volumetric flask about three-fourths full with deionized water. this was done 1 more time for the unknown and two times for the standard solution. Therefore at the end, there were 4 flasks each with 0.1 mL of sample (2-unknown and 2-standard solution).

Thanks in advance!
