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 de 7 bolsas de leche cada una con un volumen de 900m cual es la masa total de la leche expresada en kilogramos?
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
What is the meaning of the acceleration value 9.8 m/s?????
Answer:
The value 9.8 m/s^2 is the average acceleration of a falling object due to the force of gravity on Earth. The letter g represents this value the formula v=gt. With this constant and formula, the speed of an object is calculated at the time t in seconds after it is dropped.
All objects fall at the same rate of speed due to gravity, regardless of their weight. If a small grain of sand and a bowling ball are dropped at the same time, both hit the floor at the same time. The value of g varies by one's location on the planet, ranging from 9.782 m/s^2 in the Panama Canal Zone to 9.832 m/s^2 at the Noth Pole

A block of concrete has a mass of 5100 g and a volume of 2500 cm3 . Calculate the density.
Answer:
2.04 g/cm3
Explanation:
Density = mass ÷ volume
= 5100 ÷ 2500
=2.04 g/cm3

aerobic cellular respiration requires an adequate supply of
Answer:
oxygen ?
Explanation:
not sure but I think so
Aerobic cellular respiration requires an adequate supply of oxygen. In the presence of oxygen, the cell completely oxidised the glucose molecule to form ATP.
What is cellular respiration?In cellular respiration, the cell takes glucose and breaks it down to form energy. Cellular respiration is of two types: aerobic respiration and anaerobic respiration.
In aerobic respiration, the cell requires oxygen. Due to the presence of oxygen, the complete oxidation of glucose takes place. Glucose is converted into pyruvic acid and then enters the Krebs cycle and the electron transport chain to make ATP.
In the aerobic cellular respiration process, the maximum amount of ATP is derived. In anaerobic respiration, the cell performs respiration without the presence of oxygen. An example is glycolysis.
In this glycolysis process, the complete oxidation of glucose does not take place. In the absence of oxygen from pyruvate, lactic acid and ethanol are produced. This is called fermentation.
Hence, for aerobic cellular respiration, oxygen is required.

What type of decay does Am-241 undergo to become Np-237?
a. Alpha decay
c. Positron emission
b. Beta decay
d. Electron capture
The type of decay that Am-241 undergoes to become Np-237 is alpha decay. The correct option is a.
What is alpha decay?Alpha decay is a type of decay or transformation in which a nucleus emits an alpha particle and change into different atomic nuclei. The atomic number reduces by 2 and the mass is reduced by 4.
Am-241 is an isotope of the chemical element americium. It is a radioactive element and its radioactive decay period is 432.2 years. It is used in the testing of machinery.
When the nucleus of Am changes or emits a radioactive particle. It converts into Np-237. The process is called alpha decay. The atomic mass is reduced by four, and the 241 converts into 237, which become neptunium.
Thus, the correct option is a. Alpha decay.

In a lab, a scientist calculate he should produce 12.3 grams of product in his experiment. When he is finished collecting his product it weighs 11.0 grams. What is his percent yield?
Answer:
Option D.
Explanation:
Percentage yield = Actual yield / Theoretical yield * 100%
Actual yield = 11.0 grams
Theoretical yield = 12.3 grams
Percentage yield = 11.0 / 12.3 * 100
Percentage yield = 89.43%
A gas has a solubility of 1.46 g L at 8.00 atm of pressure. What is the pressure of a sample of the same gas that
contains 2.7 g/L of the dissolved gas?
Answer:
[tex]14.8\ \text{atm}[/tex]
Explanation:
[tex]C_1[/tex] = Initial concentration = 1.46 g/L
[tex]C_2[/tex] = Final concentration = 2.7 g/L
[tex]P_1[/tex] = Initial pressure = 8 atm
[tex]P_2[/tex] = Final pressure
From Henry's law we have the relation
[tex]\dfrac{C_2}{C_1}=\dfrac{P_2}{P_1}\\\Rightarrow P_2=\dfrac{C_2}{C_1}P_1\\\Rightarrow P_2=\dfrac{2.7}{1.46}\times 8\\\Rightarrow P_2=14.8\ \text{atm}[/tex]
The pressure of a sample of the same gas at the required concentration is [tex]14.8\ \text{atm}[/tex].

A mixture of Oxygen and Hydrogen occupies a pressure of 101.3kPa. The pressure of Hydrogen is 56kpa. Calculate the pressure of oxygen.
Answer:
45.3 KPa
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 101.3 KPa
Pressure of Hydrogen (Pₕ) = 56 KPa
Pressure of Oxygen (Pₒ) =?
The pressure of oxygen in the mixture can be obtained as follow:
Pₜ = Pₕ + Pₒ
101.3 = 56 + Pₒ
Collect like terms
101.3 – 56 = Pₒ
Pₒ = 45.3 KPa
Thus, the pressure of oxygen in the mixture is 45.3 KPa
