What is the molar mass of water (H2O)? a. 19.0 g/mol b. 20 g/mol c. 16.0 g/mol d. 18.0 g/mol What is the molar mass of water, H 2 O ? What is the molar mass of water? What is the formula mass of Na(NO3)2?
the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and now primarily used in the production of the “anti-stick” polymer, Teflon. The molecular ...
Suppose the solute mass is msolute (dissolved in a particular solvent), and the total mass of the solution is msolution; we consider the below expression to calculate the percent by mass of the solute. Mass%=msolutemsolution×100% The mass of solute or so...

Here, we investigate the deep ore body of the Qianchen gold deposit at the southern part of the Jiaojia gold belt based on mineralogy, fluid inclusion, elemental and isotopic composition of pyrite, and the primary halo geochemistry. Natural gold is the important form of Au in this deposit ...
To determine the impact of the water-cut of the condensate on the inhibitor injection requirement, one needs to calculate the mass of additional water this adds to the pipeline. The additional water is estimated as follows: ► Liquid water rate = (water-cut fraction, W-Cx) (condensate flow...
where n is the number of electrons per mole, μ0 is the vacuum permeability, e is the elementary charge, 〈r2〉 is the average square radius of the electron orbit, me is the electron mass, c is the speed of light in vacuum, and the negative sign reflects the repulsive tendency. While...
