1.(Chemistry) (of a physical quantity) per unit amount of substance:molar volume. 2.(Chemistry) (not recommended in technical usage) (of a solution) containing one mole of solute per litre of solution [C19: from Latinmōlēsa mass] ...
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需要转换为帕斯卡P=715 mm hg=715 /7.5x10^-3=9.533x10^4 paR为常数=8.314,若p用帕(Pa),V用升(L)为单位时,其数值为8315M=61.94 g/mol通过这个问题我也重新学习了下上学时的知识. ...
Gram Molecular Mass: The gram molecular mass is the same idea as the molar mass of a substance. The periodic table lists all of the elements' molar masses. It is the average of all of the isotopes of that element. Answer and Explanation:1 ...
Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chemical formula...
Density is commonly expressed in units of grams per cubic centimetre. Is molecular weight and mass the same? Molecular mass and Molecular weight is not the same, although they use interchangeably. ... Molecular weight, as a synonym of molar mass, is defined as the mass of a sample of ...
What is the density of helium gas? What is the molar mass of butane? What state of matter is propane? What is the density of chlorine gas? What is the molecular weight of methane? What is the density of paraffin? How many carbon atoms are in 2.12 mol of propane?
True or false? Density determines if a substance floats or sinks. True or false? Solids and liquids both have definite volume. True or false? The molar mass of water is 17.02 g/mol. In most cases, a substance has a greater density in its solid than in its liquid state....
Molecular mass is also called molecular weight. Because the mass is relative to carbon-12, it's more correct to call the value "relative molecular mass". A related term is molar mass, which is the mass of 1 mol of a sample. Molar mass is given in units of grams. ...

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 calculatio...
