Previesť 2,09 móla naoh na gramy

kyseliny sírové, budu potřebovat dvojnásobné množství molů NaOH, tj. 3 moly. To znamená, že n NaOH = 3 moly d. Nyní je třeba převést 3 moly NaOH na gramy NaOH. Mr NaOH = Ar Na + Ar O + Ar H = 22,99 + 15,99 + 1,01 = 39,99 M NaOH = 39,99 g.mol-1 m NaOH = n NaOH * M NaOH = 3 * 39,99 = 119,97 g Odpověď: K neutralizaci 1,5 molu H 2 SO 4

The SI base unit for amount of substance is the mole. 1 grams NaOH is equal to 0.025001806380511 mole. ›› NaOH molecular weight. Molar mass of NaOH = 39.99711 g/mol. This compound is also known as Sodium Hydroxide. Convert grams NaOH to moles or moles NaOH to grams.
