Mass of sodium thiosulfate is 110. g
Volume of the solution is 350. mL
Calculating the moles of sodium thiosulfate:
= 0.696 mol
Converting the volume of solution to L:
Finding out the concentration of solution in molarity:
Raul designs a device to protect a raw egg from cracking when dropped from different heights. He wants his device to be as light
weight as possible while safely from a 3-meter distance. Raul builds a device that has foam and aluminum on the outside and then tests his device. His initial prototype is made of one layer of aluminum foil and a 2 cm thick layer of soft foam.
His hypothesis was: If I throw an egg covered with 2 cm foam and 1 layer of aluminum foil from a three-meter distance, then the egg will not break because energy will be transferred but stopped by these materials.
What conclusion would he get from the experiment? Explain your answer. Was his hypothesis correct or wrong? Explain your answer Explain one way in which Raul can improve the design of his prototype using what you have learned about transferring potential and kinetic energy to conduct another round of tests
