I need help with run 2 the last three parts
ALCULATIONS Water Vapor Pressure Use the temperature of water from Run 1 to find the corresponding vapor pressure of water in Table 1. Record this vapor pressure (in mmHg) on the RESULTS sheet. Find the vapor pressure in the same way for Run 2 and 3. Record these values on the RESULTS sheet. 230 13.6 = 16.912 Pressure due to Water Column 230ML Pressure (in mmHg) due to water column = (height of water column in mm)/13.6 Find the pressure due to water column for each run and record these values on the RESULTS sheet. Pressure of H₂ 16.48 16.912 247 Pressure of H₂ gas = (barometric pressure) - (vapor pressure of water) - (pressure due to water column) Find the pressure of H₂ (in mmHg) for each run, convert to atm, then record each on the RESULTS sheet. Volume of H₂ The volume of H₂ was determined in milliliters for each run. Convert these volumes to liters and record these values on the RESULTS sheet. Temperature of H₂ The temperature of the H₂ gas is the same as the temperature of water for each run. Convert each temperature to Kelvins, then record these values on the RESULTS sheet. Moles of H₂ 16.912x! 760 For each calculation, use the values of pressure, volume and temperature you've just recorded on the RESULTS sheet. They now have the proper units of measure to be used in the ideal gas law. (pressure of H₂)(volume of H₂) (0.0821 L-atm/K-mol)(temperature of H₂) Record the moles of H₂ for each run on the RESULTS sheet. moles of H₂ 5 -=0.022
