The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formu...

Metal promoted elementary transformations on C1 mole-cules (C02, CH2O, CO), including their reversible fixation, are described. Utilization of monofunctional vs bifunctional (acid-base) complexes represents the main point in the strategy for the activation of a C1 molecule, the primary objective ...
(LO) gels, and gels with the highest concentration will be referred to as high-density (HD) gels. The TMOS/ethanol/H20 mole ratio was 1/31.2/4.6 for the LO gels and 1/7.5/1.1 for the HD gels. During experimentation, a LD gel was made by adding 0.5 ml of TMOS to a mixture of ...

These interactions provided a docking score of −4.4 kcal/mole (Figure 5B). Derivative 1 participated in two interactions (Figure 5C). The 4-hydroxyl of the β-phenyl ring in 1 hydrogen-bonded with Arg196, and the 2-phenyl ring interacted with Phe347 via π-π stacking. The docking ...
To determine the formula of the unknown gas weighing 1.25 g per liter at STP (Standard Temperature and Pressure), we can follow these steps:1. Understanding STP: At STP, 1 mole of any gas occupies 22.4 liters. This means that i
