The atomic mass of hydrogen is1.00794and that of oxygen is15.9994. Since there are two hydrogen atoms per molecule and one oxygen atom, the formula should look like this: molar mass (g) = 1.00794 g + 1.00794 g + 15.9994 g Therefore, the molar mass of H2O is18.01528 g. ...
2 atoms of oxygen Now, the calculation: Carbon C = 2 × 12.0107 g/mol = 24.0214 g/mol Hydrogen H = 4 × 1.00794 g/mol = 4.03176 g/mol Oxygen O = 2 × 15.9994 g/mol = 31.9988 g/mol Molar mass = 24.0214 + 4.03176 + 31.9988 = 60.05196 g/mol Our calculator does the same calcul...
"One mole" is close to the number of atoms in a gram of hydrogen. It’s also, by chance, a decent ballpark guess for the number of grains of sand on Earth. A mole is also a type of burrowing mammal. There are a handful of types of moles, and some of them are truly horrifying...
