# 2016-06-05 · 109 g of HCl Molarity is represented by the following equation: In our case, we already have the molarity and the volume of solution. However, the volume does not have the proper units since it is given in terms of milliliters instead of liters. We can convert 500 mL into liters by using the conversion factor 1000mL = 1L. When 500 mL is divided by 1000 mL/L, we obtain a volume of 0.50 L. Now

How many liters of hydrogen gas, measured at STP, are produced? Mg(s) + 2HCl(aq) → MgCl 2 (aq) + H 2 (g) Example 1: Density of hydrogen at 5 bara and 24 °C. Calculator gives the density at 24 °C and 1 bara: 0.0815 [kg/m 3] Density at 24°C and 5 bara: 0.0815 [kg/m 3]* 5[bara]/1[bara] = 0.408 [kg/m 3] Example 2: Density of hydrogen at 725 psia and 125 °F. Calculator gives … GAS SAMPLE DATA Volume of sample 90.0 mL Temperature 25 C Atmospheric Pressure 745 mm Hg Equilibrium Vapor Pressure of H 2 O (25 C) 23.8 mm Hg (a) Calculate the number of moles of hydrogen gas collected.

We'll learn how to convert back and A pressure of 0.428 atm is exerted on a 240 ml sample of hydrogen gas. It is then increased to. 0.724 atm. What will the final volume of the sample be? A sample of carbon dioxide gas has a pressure of 55 mm Hg in a volume of 125 mL. The sample.
