If you have a gas sample that has a mass of 0.993 g occupying 0.570 L. Given the temperature is 281 K and the pressure is 1.44 atm, what is the molar mass of the gas? A sample of gas has a mass of 38.8mg. It's volume is 224mL at a temperature of 55C and...
Why does MgO have a higher melting point than CaS? Melting point: The melting point of the substance is described as the temperature at which the substance changes from its solid form to the liquid form. At the melting point, the solid and the liquid form of the substance exist in equilib...
The basis of MALDI-TOF is mass spectrometry, which comprises three main components: an ion source to ionize and transfer sample molecules ions into a gas phase, a mass analyzer device that separates molecules depending on their mass, and a detector to monitor all separated ions. The advantages...
Previous studies have reported some risk factors for PMB-induced nephrotoxicity, such as age, baseline SCr (serum creatinine) level, body mass index (BMI), concomitant use of vasoactive drugs and vancomycin, infection site, duration of therapy, and a daily dose of 200 mg or more [7,8,18,1...
Molar volume of gases and stoichiometry Graham's Law Kinetic Molecular Theory Real gases and deviation from ideal gas law Graham's law demonstration Labs Molecular Mass of a Volatile Liquid Students use the Dumas method for determination of the molar mass of an unknown volatile liquid. ...
Also since this is a gas phase reactions, we can increase pressure to shift the reaction towards the side that has the fewest molecules which is the product side. Raising the pressure would favor more product formation, but 200...
Operation at high current densities is detrimental for the stack. During this sensitivity analysis, the hot utility remained zero because a large enough portion of the fuel electrode off-gas was sent to the afterburner (18% in molar basis). Despite the fact that at higher current densities bot...
Its melting point is an extremely high 1538 C (2800 F), while its boiling point – that is, the temperature at which liquid iron begins to evaporate and become gas – is a scorching 2861 C (5182 F). It is no wonder, then, that in metalworking, the kinds of furnaces used must be ...
The molar gas volume means the fixed volume of one mole of any gas at a specific temperature and pressure. It is expressed as the ratio between the molar mass (M) and mass density (ρ). It is also called the molar volume of the gas....
As temperature increases, how does the average speed of gas molecules change? A. Stays the same B. Depends on the gas C. It decreases D. It increases Average Speed The average speed of gas molecules is given by the formula It varies...
