Part b an "empty" container is not really empty if it contains air. how may moles of nitrogen are in an "empty" two-liter cola b
Sedbober [7]
<span>6.38x10^-2 moles
       First, let's determine how many moles of gas particles are in the two-liter container. The molar volume for 1 mole at 25C and 1 atmosphere is 24.465 liters/mole. So
   2 L / 24.465 L/mol = 0.081749438 mol
       Now air doesn't just consist of nitrogen. It also has oxygen, carbon dioxide, argon, water vapor, etc. and the total number of moles includes all of those other gasses. So let's multiply by the percentage of nitrogen in the atmosphere which is 78%
    0.081749438 mol * 0.78 = 0.063764562 mol.
        Rounding to 3 significant figures gives 6.38x10^-2 moles</span>

Una solución contiene 25.10 ml de H2SO4 (densidad de 1.34 g/ml). Calcular la molaridad, moralidad, normalidad, fracción molar de
aliina [53]

Answer:

Molaridad: 0.80 mol/L

Molalidad: 0.80 mol/kg

Xst: 0.014

Xsv: 0.986

N: 1.6 Eq/L

Explanation:

Volumen de soluto: 25.10 mL (ácido sulfúrico)

Volumen de solvente: 426 mL (agua)

Sabemos que la densidad del acido es 1.34 g/mL, por lo que podemos calcular así la masa de ácido en solución:

1.34 g/mL = masa / volumen

1.34 g/mL . 25.10 mL = 33.6 g

Con la masa molar, calculamos moles: 33.6 g . 1 mol / 98g = 0.343 moles

Molaridad: (moles de 1 soluto en 1 L de solución)

Convertimos mL a L, asumimos que el volumen de solvente es el volumen total: 426 mL . 1L / 1000 mL = 0.426 L

0.343 mol / 0.426 L =  0.80 M

No existe moralidad en Quimica, asumo que es molalilad

La molalidad señala moles de soluto en 1 Kg de solvente. Necesitamos la masa de solvente que calculamos a traves de la densidad del agua:

1 g/ mL = masa / volumen

1 g/mL . 426 mL = 426 g de solvente

Convertimos a kg → 426 g . 1 kg / 1000 g = 0.426 kg

0.343 mol / 0.426 kg = 0.80 m

Para las fracciones molares sumamos los moles de cada compuesto

Moles de soluto + moles de solvente = Moles totales

Xst = moles de soluto / moles totales

Xsv = moles de solvente / moles totales

Los moles de solvente son: 426 g . 1mol / 18g = 23.67 moles

0.343 mol st + 23.67 mol sv = 24.013 moles

Xst = 0.343 / 24.013 = 0.014

Xsv = 23.67 / 24.013 = 0.986

La normalidad señala la cantidad de equivalentes de soluto, contenidas en 1L de solución:

Se calculan los Eq como (masa molar / N° de H⁺ u OH⁻ si es base)

Eq acido sulfurico = 98 g / 2 = 49 Eq

(Dividido 2 porque son 2 H⁺)

Eq acido sulfurico en 33.6 g = 33.6 g / 49 → 0.686 Eq

N = 0.686 Eq / 0.426 L → 1.61 N

Si la cantidad de H⁺ para un acido o de OH⁻ para una base es 1:

Molaridad = Normalidad

Si la cantidad es el doble podemos decir:

2 . M = N

Si verificamos, 2 . 0.8 M = 1.6 N

What liquid is sour and can dissolve metal
LUCKY_DIMON [66]

Answer: In essence, Boyle defined alkalies as substances that consume, or neutralize, acids. Acids lose their characteristic sour taste and ability to dissolve metals when they are mixed with alkalies. Alkalies even reverse the change in color that occurs when litmus comes in contact with an acid.
