数值都不会有单位...(因为是相对于CARBON-12 ATOM) RELATIVE ATOMIC MASS的定义是某一只ELEMENT的ATOM 数量是1 MOLE 相对于1 MOLE的CARBON-12 ATOM的质量... 而1 MOLE的CARBON-12 ATOM的质量就是12g... RELATIVE MOLECULAR MASS定义跟RELATIVE ATOMIC MASS的差不多 都是相对于CARBON-12 不过用的...
The molar mass can be defined as the mass of one mole of any substance. As for a mole, that’s just the overall number of atoms in twelve grams of the carbon-12 isotope. That’s always a fixed number, often dubbed Avogadro’s number. As follows from this, the molar mass of any s...
An organic compound is any member of a large class of chemical compounds whose molecules contain carbon. Themolar mass When an organic compound is given as a molecular formula, Dr. CHON wants to find its molar mass. A molecular formula, such asC3H4O3, identifies each constituent element by it...
8.1 Molar Mass The molar mass (molecular weight) of a hydrate can be determined from its crystal structure and the degree of saturation. The molar mass of the hydrate, M, is given by: (8.1)M=NWMW+∑j=1c∑i=1nYijνiMjNW+∑j=1c∑i=1nYijνi where NW is the number of water mole...

mass of carbon dioxide using the equation above. One complication is that weighing the carbon dioxide gas is hard; you can’t simply tare the balance and add carbon dioxide. You will need to figure out the mass of the air inside the flask and subtract that off of the mass of the flask...
英语化学求分子式和试验试!A compound contains only carbon,hydrogen,and oxygen.Combustion of 10.68 mg of the compound yields 16.01 mg CO2 and 4.37 mg H2O.The molar mass of the compound is 176.1 g/mol.What are the empirical and molecular for
Reaction kinetics was monitored by measuring the molar mass distribution (DP ~ 30…3500) and formation of short oligosaccharides (DP < 6) under mild conditions (T = 50 °C…80 °C, cHCl = 0.05…0.25 M). Accuracy of the molar mass determination using analytical ...
