The average quadratic velocity of a gas molecule is given by the equation v = sqrt(3RT/M), where R is the universal gas constant (8.314 J/mol*K) and M is the molar mass of the gas. To find the value of v, we first need to convert the mass and volume units to SI units (grams to kilograms and liters to cubic meters). Therefore, the mass of the gas becomes 0.01 kg and the volume becomes 0.027 m^3. Now, we can plug these values into the equation, along with the given pressure (10 Pa) and the molar mass of the gas, which can be calculated by dividing the mass of the gas by its molar amount (10 g/mol) to get M = 0.001 kg/mol. Finally, solving the equation gives us an average quadratic velocity of 502.07 m/s. So, if you are ever in a gas with these parameters, watch out for those fast-moving molecules!
