Por qué los alimentos se dañan con mayor facilidad a temperatura ambiente que cuando están en la nevera?
ella [17]

Answer:

Esto se debe a que la heladera tiene mucha menor temperatura que la temperatura ambiente.

Esta menor temperatura ayuda a luchar contra los microorganismos que están en los alimentos (bacterias, hongos, etc) pues detiene en gran medida su repreduccion, la cual se ve maximizada en los rangos entre 5°C y 60°C, tal que la temperatura ambiente suele estar en el rango donde los microorganismos prosperan y se reproducen, es por ello que los alimentos se conservan mucho mejor en ambientes fríos (como la nevera) que en temperatura ambiente.

How many liters of water are needed to make a 4.00 M solution using 75.0
timurjin [86]

Answer:

0.22L

Explanation:

Given parameters:

Concentration of solution  = 4.00M

Mass of lithium Bromide  = 75g

Unknown:

Volume of water  = ?

Solution:

Concentration in terms of the molarity is the number of moles of solute in a solution.

   Molarity  = \frac{number of moles }{volume of solution}

let us find the number of moles first;

Number of moles  = \frac{mass}{molar mass}  

  Molar mass of LiBr =  7 + 80  = 78g/mol

                                 number of moles  = \frac{75}{78}

                                 number of moles  = 0.96moles

Volume of water  = \frac{number of moles }{molarity}   = 0.96/4 = 0.22L
