An isolated insulated cylinder contains 15.40 grams of neon gas and a 62.30-gram bronze medal in thermal contact. When the bronze medal was put into the cylinder, its temperature was 72.30°C. The final temperature of both the medal and the neon gas is 66.30°C. Neon’s specific heat capacity is 1.047 joules/gram degree Celsius, and bronze’s specific heat capacity is 0.3770 joules/gram degree Celsius. What was the initial temperature of the neon? Type the correct answer in the box. Use numerals instead of words. Express your answer to the correct number of significant figures. The initial temperature of the neon gas was °C.

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
