The concept of the mole helps to put quantitative information about what happens in a chemical equation on a macroscopic level. For example, in the chemical reaction 2H2O→ O2 + 2H2, two moles of water are decomposed into two moles of molecular hydrogen and one mole of molecular oxygen. Th...

(500–1000 femtomoles for PC). Therefore, we designed an EAD spectral annotation program to rank candidates from the well-characterized lipid chemical space (see Supplementary Methods for the targeted chemical space), rather than to discover new structures. This enables one to perform a ...
The aim is to study the coupling between a continuum ensemble of particles that participate into a small number of rare events, representing the binding of a small and finite tiny subset of these Brownian mole- cules to small targets. It was already noticed that discrete-state stochastic models...

Number of neutrons in the nucleus of the Sodium ion = 12 The atomic mass of Sodium $=11+12=23$ Hence, 1 mole of Sodium weighs 23 grams.We know,Since the atomic mass of Sodium is 23, we can also write it as 23 g/mol.Therefore, we conclude that...
EXPERMENTAL PROCEDURE Materials Three types of salmon milt-based DNA were used throughout this study: (i) low-molecular weight DNA (LMw-DNA; molecular weight B20 000 Da, single-stranded), (ii) intermediate-molecular weight DNA (IMw-DNA; mole- cular weight B50 000–100 000 Da, mostly ...
X-ray diffraction analysis on a solid sample of 1b, prepared from a solution in chloroform, provides detailed parameters supporting the stacking of the macrocyclic molecules into nanotubes (Supplementary Fig. S5). The diffractogram reveals a dominant peak at 28.08 Å and two other ...
