**Question 3 of 3**A 30.0 g sample of O₂ at standard temperature and pressure (STP) would occupy what volume in litres?---**Explanation:**At the bottom of the screen, there is a numeric keypad for entering responses. It includes numbers 0 to 9, a decimal point (.), and a plus/minus (-/+) button. There are also buttons for deleting entries (backspace), clearing the input (C), and a button for scientific notation (x10).The question asks for the volume of an oxygen sample (O₂) given in grams, to be calculated under the conditions of standard temperature and pressure, a common reference point in chemistry.

Standard temperature and pressure means, temperature is 273 K and pressure is 1 atm. Therefore---- Pressure (P) = 1 atm Temperature (T) = 273 K Mass (g) = 30 g Molar mass of O2 (M) = 32 g /mol So, Mole (n) = [Mass/Molar mass] = [30/32]mol = 0.9375 mol Gas constant (R) = 0.0821 litre atm / K / mol Volume (V) =?We know, the formula---- P V = n R T Or, V = [n R T] / [P] Or, V = [0.9375 x 0.0821 x 273] / [1] Or, V = 21.01 L Answer--- Volume (V) = 21.01 L

An atom of argon has a radius Ar = 71. pm and an average speed in the gas phase at 25°C of 249.m/s. Suppose the speed of an argon atom at 25°C has been measured to within 1.0%. Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of Ar and round it to 2 significant figures. For example, if the smallest box the atom could be in turns out to be 42.0 times the radius of an atom of argon, you would enter "42. Ar" as your answer. Ar X ?

This law is only valid when the behavior of a gas is idealized according to three principal assumptions. (i) State the three assumptions made about an ideal gas, and for each assumption (ii) explain which physical property of a gas would be affected if that assumption was not made.
