The accepted value of ksp is 1.2×10^−12 for Ag2CrO4. Calculate the percentage error if your experimentally determined value for
sweet-ann [11.9K]
%error = |(original value - mistaken value)| / original value * 100%

Original value = 1.2 x 10^-12
Mistaken value = 1.7 x 10^-10

%error = | [(1.2 x 10^-12) - (1.7 x 10^-10)] | / 1.2 x 10^-12 x 100%

%error = (1.688 x 10^-10 / 1.2 x 10^-12) x 100%

%error = 1.172222222 x 10^17

La leche se considera un alimento basico por su elevado contenido de nutrientes su densidad es de 1,4g/ml. Si se hace una compra
noname [10]

Answer:

8.82 kg es la masa total de leche

Explanation:

Consideraremos que el volumen de cada bolsa de leche es de 900 mL.

Sabiendo que tenemos en total 7 bolsas, el volumen final en litros que tenemos disponible es de:

900 mL . 7 = 6300 mL

Utilizando la densidad podemos calcular la masa de leche que tenemos en el total de las 7 bolsas

Densidad = masa / volumen

Densidad . volumen = masa → 1.4 g/mL . 6300 mL = 8820 g

Convertimos la masa de gramos a kg

8820 g . 1 kg /1000g = 8.82 kg

The mass of an atom of beryllium is 1.5 x 10^-26 kg. How many beryllium atoms are present in beryllium film of mass 0.37 g used
timama [110]

Answer:

There are 2.5 * 10^22 beryllium atoms in 0.37 grams

Explanation:

Step 1: Data given

The mass of an atom of beryllium is 1.5 x 10^-26 kg.

Total mass = 0.37 grams

Step 2: Calculate number of atoms

1 atom = 1.5 * 10 ^-26 kg

X atoms = 0.00037 kg

X = 0.00037/1.5*10^-26

X = 2.467 * 10^22 atoms ≈ 2.5 * 10^22 atoms

There are 2.5 * 10^22 beryllium atoms in 0.37 grams
