Answer:
Ok:
Explanation:
So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.
Answer:
![V_2=36.84L](https://tex.z-dn.net/?f=V_2%3D36.84L)
Explanation:
Hola,
En este caso, podemos usar la ley de Boyle, la cual nos permite analizar el comportamiento volumen-presión en un gas ideal de manera inversamente propocional:
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
Así, dado el volumen y la presión inicial, la cual se convierte a atmósferas (760 torr = 1atm), calculamos el volumen final a 1 atm como se muestra a continuación:
![V_2=\frac{P_1V_1}{P_2}=\frac{700torr*\frac{1atm}{760torr}*40l }{1atm}\\ \\V_2=36.84L](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7BP_1V_1%7D%7BP_2%7D%3D%5Cfrac%7B700torr%2A%5Cfrac%7B1atm%7D%7B760torr%7D%2A40l%20%7D%7B1atm%7D%5C%5C%20%20%5C%5CV_2%3D36.84L)
Saludos!
Solid- molecules vibrate in place and tightly packed
liquid-molecules fur shape of container and can slide past each other
gas-molecules also fit shape of container and have the most room
It's an ionic bond! Potassium is a cation, or a metal with a positive charge, and fluoride is an anion, or a nonmetal with a negative charge.
A covalent bond is the bond between two nonmetals.
Hope this helped!
