The liberated oxygen has been analyzed mass spectrometrically and O 18/O 16 ratios reliable to within 0.05% have been determined for a number of natural silicates. The results indicate that differences as high as 2.4% exist in the O 18/O 16 ratios of the silicate oxygen contained in the ...
two gases, it will also represent on our hypothesis the ratio of the masses of their molecules. Thus the mass of the molecule of oxygen will be about 15 times that of the molecule of hydrogen, or more exactly, as 15.074 to 1. In the same way the mass of the molecule of nitrogen...

3. relative yield and salt mass per unit area vs. 在搜集、统计大量咸水灌溉试验资料的基础上,选取咸水充分灌溉条件下矿化度和小麦产量的完整对应数据103组,统计分析了灌溉水矿化度及单位面积盐分带入量对小麦相对产量的影响,结果表明,随着灌溉水矿化度的增加,小麦相对产量呈线性递减趋势,当矿化度大于1。
mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen ...
The inadequacy of oxygen as an arbitary standard led to the selection of the carbon-12 isotope of carbon as the arbitary standard. The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. ...
of the mass of an atom of carbon-12 (known as the unified atomic mass unit). You need to calculate the relative atomic mass of a molecule, which consists of one or several atoms. In this problem, you only need to process molecules which contain hydrogen atoms, oxygen atoms, and carbon...
The ancestors could have chosen 1/1 the mass of a hydrogen atom, or 1/16 of an oxygen atom, or 1/59 of a cobalt atom, 1/232 of a thorium atom... Choosing an element that consists essentially of a single isotope makes sense. Then, as nucleons don't weigh exactly as much in all...
