Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m

Finally, μCT can also be used to quantify the mass and 3D spatial distribution of bone mineral in addition to tissue morphology. The mass of mineral within each bone voxel can be calculated from the X-ray attenuation using calibration phantoms. The TMD is calculated as the mass of mineral/...
law, it is possible to determine the value of any of the four variables knowing the other three. Mass can even be used as one of the variables since it has a relationship with moles. The molar mass and density of a gas can be determined from the ideal gas law. CONTINUE ON NEXT PAGE...
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. ...
The dependency of the molar volume of the system on composition is known from the density measurement. There are few methods for high-temperature density measurement as the corrosive nature of molten salts and the thermal dilatation of the materials are used for measurement. The most convenient ...
molten Ni-based commercial al- loys can be calculated from the molar mass and the density data of the alloys by the following equation: V mol = M Alloy ρ Alloy (8) Where Vmol, MAlloy and ρAlloy stand for the molar volume, the molar mass and the density of the alloy, respectively...

a sample of gas has a density of 1.96g/l at STP.Determine its molar mass. 扫码下载作业帮搜索答疑一搜即得 答案解析 查看更多优质解析 解答一 举报 1.96克密度/升,STP下1mol气体的体积为22.4L所以1mol该气体质量为:1.96g/L×22.4L=43.904g≈44g所以该气体摩尔质量为44g/mol 解析看不懂?免费查看同类...
Among them, the density ρ is the density of the liquid solution, which can be obtained through experimental measurement; the relative molecular mass M is the relative molecular mass or molar mass of the solute, which can be obtained from chemical equations or related literature. North and South...
