The gases in a mixture have the following partial pressures at the same volume and temperature 1013000 Pa nitrogen 700 mmHg argon 1.20 ATM of helium 790 torr oxygen and 0.50 ATM of carbon dio?
To calculate the total pressure of the mixture, first convert all the partial pressures to the same unit (e.g., Pascals), and then add them together. Once you have converted all partial pressures to the same unit, add up all the pressures to get the total pressure of the gas mixture.
A one gram sample of aspirin contains 75.2 percent by mass of C9H8O4 How many moles of acetylsalicylic acid are in the sample?
To determine the number of moles of acetylsalicylic acid in the sample, we first need to calculate the molar mass of C9H8O4 (aspirin). Molar mass of C9H8O4 = (912) + (81) + (4*16) = 180.16 g/mol Next, we calculate the mass of acetylsalicylic acid in the sample: Mass of acetylsalicylic acid = 75.2% of 1 gram = 0.752 grams Finally, we find the number of moles using the formula: Number of moles = Mass / Molar mass Number of moles = 0.752 g / 180.16 g/mol ≈ 0.0042 moles Therefore, there are approximately 0.0042 moles of acetylsalicylic acid in the sample.
