if it dissolves in water the ions fade away. Water molecules will surround the ions, to form hydration sphere around the ions of lithium bromide in a solution. Ions instead of interacting with each other will start interacting with water molecules by which they will get dissolvoved in water
Respuesta:
14,9 g
Explicación:
Paso 1: Calcular los moles de gas
Una garrafa contiene 9 L de gas a 18°C (291 K) y 780 Torr. Podemos encontrar los moles de gas (n) usando la ecuación del gas ideal.
P × V = n × R × T
n = P × V/R × T
n = 780 torr × 9 L/(62,4 Torr.L/mol.K)/ × 291 K = 0.387 mol
Paso 2: Calcular la masa molar del gas
El gas tiene una densidad (ρ) de 2 g/L a 80 °C (353 K) y 1,5 atm. Podemos calcular la masa molar (M) del gas usando la siguiente fórmula.
ρ = P × M / R × T
M = ρ × R × T / P
M = 2 g/L × (0.082 atm.L/mol.K) × 353 K / 1,5 atm = 38,59 g/mol
Paso 3: Calcular la masa del gas (m)
Usaremos la siguiente formula.
m = n × M = 0.387 mol × 38,59 g/mol = 14,9 g

Hello.
The answer is 1417.7
Its 1417.7 grams becasue you have to convert the moles to grams.
<span /><span><span>A mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.023 X 1023).
</span><span>a coherent, typically large body of matter with no definite shape.
