Step 1: Calculate Mass Nitrogen and oxygen gas are diatomic, so the molar mass is To calculate the mass of 1 mole of air is Thus 1 mole of air weighs 0.02880 kg. Step 2: Calculate Volume To calculate the volume of 1 mole of air at NTP Step 3: Calculate Density The density of ai...
ρair=density of air(normally at NTP - 1.204 (kg/m3)) NTP - Normal Temperature and Pressure- defined as20oC (293.15 K, 68oF)and1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) Molecular weights can be used to calculate Specific Gravity if the densities ...
Here, we designed a pyroelectric nanogenerator by absorbing optical energy as surface enhanced Raman scattering (SERS) substrate for in-situ monitoring the complete oxidation reaction from 4-aminothiophenol (4-ATP) to 4-nitrothiophenol (4-NTP) and the oxygen reduction reaction (ORR) intermediates. ...

The molecular structure consists of a cyclic hydrocarbon ring with hydroxyl groups and a methyl group attached to the carbon atoms. The compound includes carbon-hydrogen and carbon-oxygen bonds, giving it its characteristic properties. L-Menthol was first isolated in 1771 from peppermint oil by ...
The higher the density, the tighter the particles are packed inside the substance. Density is a physical property constant at a given temperature and density can help to identify a substance.Densities and material properties for common materials Relative Density (Specific Gravity)Relative density of ...

Analysis of the geometry of the most favorable TS-mn shows that the two oxygen atoms of the sulfonyl group of the vinyl sulphone 20 are located at 2.27 and 2.35 Å from two methylene hydrogens of the proline residue (see Figure 5). These short distances suggest the presence of two HBs...
At high altitudes, the amount of oxygen in the air per unit volume is lower, because there is less air in total. Therefore, if climbers decide to reach the tops of the highest mountains, they usually need an oxygen cylinder with a mask to be able to breathe. This problem doesn't ...
