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

Answer:
The mass of gold is found to be 310.34 g.
Explanation:
We have:
Specific heat of gold = C = 0.130 J/g.°C
Heat = H = 468 J
Change in Temperature = ΔT = 33.2 °C - 21.6 °C = 11.6 °C
Now, to find mass of gold we first calculate the amount of heat required to heat the unit mass of gold to specified temperature:
Mass Specific Heat = C * ΔT
Mass Specific Heat = (0.130 J/g.°C)(11.6 °C)
Mass Specific Heat = 1.508 J/g
Now, for the mass of gold (m):
mass of gold = Heat/Mass Specific Heat
mass of gold = 468 J/1.508 J/g
<u>mass of gold = 310.34 g</u>
Answer:
The usage is explained below
Explanation:
Amines are identified from the use of the hinsberg reaction whereby the amine is mixed well with Hinsberg reagent and done in the presence of an aqueous alkali. In this reaction, the amine will attack the electrophile which will result in the chloride being displaced and the amides being generated.
The uses of identification of amines in daily life are;
- In agriculture, it serves as a good source of making herbicides as well as acting as emulsifiers.
- In medicine, it is used in the manufacture of some popular pain killers like demerol and morphine.
- In medicine, it is used in the manufacture of an anesthetic drug known as novocaine.
- In chemical industries, amines are used as lubricating oils and also as corrosion inhibitors in boilers.
