\({\%~of~an~element} = \frac{mass~of~an~element~in~the~compound}{relative~formula~mass~M_r} \times 100\) There are six atoms of hydrogen in the compound, so the mass of hydrogen is 6 × 1 = 6.

We are elated that the Expanse supercomputer is involved in the expansion of ChemCompute as this type of project aligns with ...

When I need to do a quick conversion, I use Calculator Soup, a simple website offering hundreds of purpose-built calculators ...

The time resolved quantum chemistry calculations are the first to exceed an exaflop — more than a quintillion calculations per second — using double-precision arithmetic. The 16 decimal places ...

\(concentration~in~g~dm^{-3}=\frac{mass~of~solute~in~g}{volume~in~dm^{3}}\) The units for concentration are also shown as g/dm 3, but this means the same as g dm-3. 8 g of sodium hydroxide is ...

The project illustrates the potential of large-scale calculations to revolutionize how scientists approach challenging ...

Though the calculation focused on the "Hartree-Fock" approximation of a real chemical system, it was twice as large as previous chemistry calculations on a quantum computer, and contained 10 times ...
