Okay, Candido. Let's look at question 2 from PART I. The question asks: "O volume molar diz que, em..." (The molar volume says that, in...) Step 1: Understand the concept of molar volume. The molar volume of a gas is the volume occupied by one mole of that gas. At Standard Temperature and Pressure (STP), which is 0^ (273.15 K) and 1 atmosphere (atm) of pressure, one mole of any ideal gas occupies approximately 22.4 liters. Step 2: Evaluate the given options. A 1 mol contém 22,4 g (1 mol contains 22.4 g): This is incorrect. 22.4 g is a mass, not a volume, and the mass of 1 mole varies for different substances. B 2 mol contém 22,4 L (2 mol contains 22.4 L): This is incorrect. 22.4 L is the volume for 1 mole of gas, not 2 moles. C 1 mol contém 22,4 L (1 mol contains 22.4 L): This is correct. This is the definition of molar volume for an ideal gas at STP. D 1 mol contém 22,4 ml (1 mol contains 22.4 ml): This is incorrect. 22.4 ml is much smaller than 22.4 L. The correct option is C. 3 done, 2 left today. You're making progress.
