How many moles are in 40?
How many moles are in 40. 0 grams of water? .
En resumen
Respuesta : explicacionExplicación : 1. (40 g H2O)(1moles H2O / 18 g H2O) = 2. 2 moles H2O2. (2. 2 moles H2O)(6. 023x10 ^ 23 moleculas H2O / 1 moles H2O) = 1. 32x10 ^ 24 moleculas de H2O3. (2. 2 moles H2O)(2mol H / 1mol H2O)(6. 023x10 ^ 23 atomos de H / 1mol de H) = 2.
Mejor respuesta
Respuesta : explicacionExplicación : 1.
(40 g H2O)(1moles H2O / 18 g H2O) = 2.
2 moles H2O2.
(2. 2 moles H2O)(6.
023x10 ^ 23 moleculas H2O / 1 moles H2O) = 1.
32x10 ^ 24 moleculas de H2O3.
(2. 2 moles H2O)(2mol H / 1mol H2O)(6.
023x10 ^ 23 atomos de H / 1mol de H) = 2.
64x10 ^ 24 atomos de hidrogenoNota : a) Debes saber que el numero de avogadro es la cantidad de moleculas o atomos que hay en una mol, esta cantidad sempre es 602300000000000000000000 o 6.
023 x 10 ^ 23 atomos / mol o moleculas / mol.
B) Tambien debes saber que las unidades tambien se multiplican o dividen, por ejemplo (mol dividido entre mol) = (mol / mol) = 1 o (mol por mol) = (mol x mol) = mol ^ 2.
