2.10
The 0 after 1 is not significant and does not affect the value of the number; therefore, when the number will be rounded to two significant figures, it will become 2.1, so it will be the same.
<span> la gravedad en la tierra no es constante ni mucho menos porque depende de la distancia al centro de la tierra... y la tierra no es perfectamente esferica </span>
<span>respecto a la pregunta, la presion atmosferica viene siendo proporcional al peso que el aire ejerce sobre nosotros. Mientras mas gravedad hay en un planeta, mayor es la presion atmosferica a cierta altura. </span>
<span>Ahora, en un mismo planeta, la aceleracion de gravedad disminuye con la altura (porque se esta mas lejos del centro) y la presion tambien disminuye con la altura, porque hay menos aire sobre nuestras cabezas. </span>
<span>espero q te sirva.</span>
Given which are missing in your question:
the flask is filled with 1.45 g of argon at 25 C°
So according to this formula (Partial pressure):
PV= nRT
first, we need n, and we can get by substitution by:
n = 1.45/mass weight of argon
= 1.45 / 39.948 = 0.0363 mol of Ar
we have R constant = 0.0821
and T in kelvin = 25 + 273 = 298
and V = 1 L
∴ P * 1 = 0.0363* 0.0821 * 298 = 0.888 atm
ANSWER: 23064 mg
EXPLANATION: To convert grams to milligrams, we multiply by 1000.
23.064 g x 1000 = 23064 mg
Hydrolysis of ATP provides the energy that is needed to drive the electrolytes pumps. Energy is needed for these pumps to function because they are active form of transportation which the body use to move electrolytes from one point in the body to the other.
