moles of Hydrogen are in a 2605ml sample at 38 oC and 735 torr
How many moles of hydrogen are present in a 31.06 mL sample at 31.60 degrees Celsius and 772.2. torr? Assume the hydrogen is dry.
A 99.3 g sample of O2 gas at 0.0 oC and 380 Torr is compressed and heated until the volume is 3.99 L and the temperature is 27 oC. What is the final pressure in Torr? The number of significant digits is set to 3
78 L of gas is at a pressure of 735 torr. What is the volume in liters (L) when the pressure decreases to 700.0 torr?

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 hydrogen gas occupies a volume of 9.64 L at 58.0°C and 312 torr. If the volume of the gas sample is decreased to 8.05 L, while its temperature is decreased to –9.0°C, the resulting gas pressure will be torr.
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)
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
