The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called...

The biochars before (BC, Mg-BC, Mg-PBC) and after (BC-P, Mg-BC-P, Mg-PBC-P) adsorption of P and a kind of commercial P fertilizer (Stanley) were mixed with the experimental soil at the ratio of 1% (mass ratio). At the same time, the soil without adding any material was ...
molecular formula of malathion. This peak, as depicted in Fig.17a, was relatively weak. Notably, the parent ion underwent a transformation through the cleavage of the S–CH bond, resulting in the formation of two extremely abundant fragments, observed at m/z 125 and 173. The mass spectrum ...
(1), VO∗∗ is an inevitable consequence of acceptor doping and the benefit is that the generated VO∗∗ could promote mass transfer and lower sintering temperature noticeably [35]. Nonetheless, the benefit is at the cost of resistivity since VO∗∗ usually leads to higher dielectric...
