A sample of N2(g) was collected over water at 25 oC and 730 torr in a container with a volume of 340 mL. The vapor pressure of water at 25 oC is 23.76 torr. What mass of N2 was collected? Answer is: 0.36 g
An aqueous chemical reaction produces hydrogen gas with a total pressure of 295.0 torr at 17.5 oC in a closed container. What is the partial pressure of the hydrogen gas if the water vapor pressure is 15.0 torr at 17.5 oC and external atmospheric pressure is 760.0 torr? Mg(s) + 2HCl(aq) ⟶H2(g) + MgCl2(aq)
A sample of 8.00 L of NH3 (ammonia) gas at 22 degrees and 735 torr is bubbled into a 0.500 L solution of 0.400 M HCl (hydrochloric acid). The Kb value for HCl is 1.8x10^-5. Assuming all the NH3 dissolves and that the volume of the solution remains at 0.500 L, calculate the pH of the resulting solution. (need some help kinda dont know where to start)
A gas sample containing 1.42 moles at 23°C exerts a pressure of 450. torr. Some gas is added to the same container and the temperature is increased to 40.°C. If the pressure increases to 800. torr, how many moles of gas were added to the container? Assume a constant-volume container.
Part A A sample of hydrogen gas is mixed with water vapor The mixture has a total pressure of 759 torr, and the water vapor has a partial pressure of 26 torr What amount (in moles) of hydrogen gas is contained in 1.73 L of this mixture at 298 K? Express the amount in moles to three significant figures. O ALO O 2 ? amount = mol Submit Request Answer
