Molar Mass of a Gas:We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but the molar mass of the gas can also be calculated from the same equation. Like any other calculati...
The volume of a gas is a function of both pressure and temperature. At STP, 1 mol of gas occupies 22.4 liters (L) of volume. In other words, the molar volume of a gas at STP is 22.4 L. This volume can be found using the ideal gas law: PV=nRT (n = number of moles, R = ...
and 715 mm Hg.What is the molar mass of the gas? 相关知识点: 试题来源: 解析 理想气态方程(克拉伯龙方程)PV=NRT由N=m/M ,PV=(m/M)RT,左边移过来,右边移过去就是PM=pRT p为密度.M即为molar mass分子质量.这里p=2.39 g/lT需要由摄氏温度转变为开氏温度T=23.0℃=273.15+23℃=296.15KP需要转...
The metric system uses the liter (L) as a volume unit. One liter is the same volume as a 10-centimeter cube. Volume Examples Read More Secrets of Molar Volume in Chemistry By Anne Marie Helmenstine, Ph.D. As a volume example, a student might use agraduated cylinderto measure volume of...
The specific volume is an intensive property of a substance. The specific volume of an object is defined as the ratio of the volume of the object to the mass of the object. It is the volume occupied by the unit mass of an object....
After 1.00 mL of water is completely vaporized to gas, how many milliliters of vapor are produced at standard temperature and pressure? (Density of water is 1.00 g/mL; the molar volume of any gas at STP is 22.4 L/mol). How many milliliters of water would you need to make a 10-2...
This means that if we know the volume of gas and its mass, we can find its molar mass. 2. Identify Given Values: - Volume of gas = 5.6 liters - Mass of gas = 12 grams - Molar volume at STP = 22.4 liters 3. Set Up the Proportion: We know that: Molar mass (g)=(mass of ...
Derive the expression and solve it.If a gas obeys van der Waals equation(P + a/V2)(V-b) = RTprove that (∂U/∂V) at constant temperature =a/V2.What is the expected boiling point of water at 98.7 kPa.The heat of vaporization is 2258 Jg-1,the molar volume of liquid water ...
What is the molar mass of sucrose? Calculating the Molar Mass of a Compound: In order to calculate the molar mass of any compound, we only need to know what elements are contained in the compound and what the molar mass of the elements are. ...
