How many grams of helium are contained in a 2.0 L balloon at 30 degrees Celsius and at 735 mm Hg?
To find the number of grams of helium in the balloon, you need to use the ideal gas law equation. First, convert the temperature to Kelvin by adding 273 (303 K). Then, convert the pressure to atm (0.966 atm). Now, use the ideal gas law formula: PV = nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant, and T is temperature in Kelvin. Solve for n (moles), which equals 0.08 moles of helium. Finally, calculate the mass using the molar mass of helium (4 g/mol) multiplied by the number of moles (0.08 mol), which equals 0.32 grams of helium.
