A massa molar é a massa em gramas de um mol de entidades elementares – átomos, moléculas, íons, elétrons, outras partículas ou outros grupos específicos de tais partículas. É representada pela letra "M" e expressa na unidade g/mol. H = 1 g – como existem dois átomos de H na fórmula química da água então o valor seria igual a 2 g. Massa molar de H₂O = 2 g + 16 g = 18 g/mol. O mol é a unidade usada para converter da u… Web1 de set. de 2024 · Referring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable “ballpark” estimate of the number of moles would be slightly greater than 0.1 mol. canon print in black only
