Molens masse (M) for et stof er massen af et mol af det stof. For et molekyle beregnes molmassen ved at multiplicere abonnementet på hvert element med dets molmasse, hvilket er dets atomvægt på det periodiske system i g / mol. C2H5OH er formlen for ethanol.
Molar mass of ethanol (C2H5OH) is:(Atomic masses: C
WebVolume of ethyl alcohol (C2H5OH) = 516 mL Density = .789 g/mL Mass of beaker = .245 kg Solution: We will use the formula for density in order to get the mass of C2H5OH = density x volume M (C2H5OH) = .789 g/mL x 516 mL = 407.124 g Then mass total = mass-beaker + mass- C2H5OH Mass total = 245g+407.124g WebMassa Molecular ( peso molecular ) é a massa de uma molécula de uma substância e é expressa nos unificadas unidades de massa atómica (u).
