A mixture of hydrogen and helium gases, at a total pressure of 844 mm Hg, contains 0.464 grams of hydrogen and 0.585 grams of helium. What is the partial pressure of each gas in the mixture

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
