The meaning of MOLECULAR is of, relating to, consisting of, or produced by molecules. How to use molecular in a sentence.
molecular weight- (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule relative molecular mass mass- the property of a body that causes it to have weight in a gravitational field chemical science,chemistry- the science of matter; the branch of the natural ...
If the atomic mass of hydrogen is taken as 1, the relative atomic mass of oxygen is 16. Initially, scientists obtained the atomic masses of all the elements by comparing with the mass of hydrogen taken as 1. However, the problem was that the atomic masses of most of the elements came ...
Molecular mass of carbon dioxide (CO2) = ( Atomic mass of carbon C) + ( Atomic mass of Oxygen) x 2 = ( 12 x 1 ) + (16 x 2) = 44g/mole The molecular mass of carbon dioxide CO2 is 44 g/mole. Suggest Corrections 145 Similar questions Q. Calculate the molecular mass of the fo...
For both samples, our measurements show a two-stage devolatilization phase separated by a char-oxidation phase which can be attributed to the interaction of oxygen consumption in the gas phase and on the surface and the release of volatiles from deeper layers of the plate. Furthermore, detailed...

因为相对) FORMULA MASS就是指1 MOLE的IONIC COMPOUND(GIANT IONIC STRUCTURE)的质量 单位是gmol^-1 MOLAR MASS就是指某ELEMENT的1 MOLE ATOM的质量 单位是gmol^-1 好啦 举点例子啦-V- 1 MOLE的SODIUM ATOM的RELATIVE ATOMIC MASS就是23.0 MOLAR MASS就是23.0gmol^-1... 1 MOLE的OXYGEN GAS...
Let us not bother about the numbers but instead call this amount a mole. Oxygen was the best candidate to define a mole. •The most universal atom at the time was oxygen. •About 50% of the earth crust is oxygen. •Oxygen can react with all the other atoms. Let us weigh 32 gr...
