Calculate the temperature of 4.00 moles of ideal gas at a pressure of 2.00 atm and a volume of 54.0 L. (Use 0.0821 L · atm/mol · K as the gas constant.)

Determine what happens to the pressure of the above sample of ideal gas if the volume is halved and the temperature doubles.

A student states that if the volume of a sample of ideal gas increases to three times the original volume, and the pressure also increases to three times the original pressure, the temperature of the gas will remain unchanged

-Explain why the student is incorrect.
- Determine the actual temperature of the ideal gas.

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.

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
