Question

M (H2O)= 18*10^-3 кг/моль. m0=?

Answer 1

$\displaystylem_0 = \frac{M}{N_A} = \frac{18\cdot10^{-3}}{6\cdot10^{23}} = 3\cdot10^{-26}$ кг

Answer 2

In the given equation, "M(H2O)" represents the molar mass of water, which is approximately 18.0 grams per mole or 18.0 * 10^-3 kilograms per mole. However, it seems that you are looking for the molar mass symbolized as "m0." If "m0" refers to the molar mass of another substance, please provide the appropriate chemical formula or name of the compound so that I can assist you further.
