Web19 feb. 2024 · Now, in the given question, to get the equal number of molecules as that of 2 moles of \[{H_2}O\], we would need exactly two moles of methanol. Molecular weight of methanol is equal to 32 g i.e. Weight of one mole of methanol = 32 g Hence, weight of two moles of methanol = 2 $\times$ 32 g = 64 g Thus, the correct answer is 64 grams.
