Web08. mar 2024. · You can calculate the MW of the acid by referring to a periodic table to get the MW of each element and adding 2 (1) + (32) + 4 (16) = 98.0. Note that this acid can donate two protons, as the sulfate ion is left with a charge of −2. This the equivalent weight is 98.0/2 = 49.0. For a base, the reasoning is the same. WebAmines with low molecular weight are used as curing agents. Due to the limitation of viscosity adjustment, high workability cannot be expected. However, because it does not contain solvents, it is used for thick film coating and for coating in enclosed spaces as a fire accident prevention measure. ...

The dispersity of a polymer sample if often between 1 and 2 (although it can be even higher than 2). The closer it is to 1, the narrower the distribution. disney wilderness lodge orlando
