Mass/volume = density. We know the volume (5 cm cubed) and the density (8.96). We plug these into the equation to find the mass:

M/5 = 8.96

M = 44.8 grams

Answer:

n_{N_2}=6.41mol

Explanation:

¡Hola!

En este caso, teniendo en cuenta la información dada por el problema, inferimos que primero se debe usar la ecuación del gas ideal con el fin de calcular las moles de gas que se encuentran al inicio del experimento:

PV=nRT\\\\n=\frac{RT}{PV} \\\\n=\frac{0.08206\frac{atm*L}{mol*K}*(50.0+273.15)K}{740/760atm*4.25L}\\\\n=6.41mol

Seguidamente, usamos la ley de Avogadro para calcular las moles finales, teniendo el cuenta que el volumen final es el doble del inicial (8.50 L):

n_2=\frac{6.41mol*8.50L}{4.25L}\\\\n_2=12.82mol

Quiere decir que las moles de N2(g) que se agregaron son:

n_{N_2}=12.81mol-6.41mol\\\\n_{N_2}=6.41mol

¡Saludos!

ASAP<br>what is an electron cloud ​
Bad White [126]

Explanation:

An electron cloud is the region of space that surrounds the nucleus of an atom under the nucleus of the negatively charged sub-atomic particles.

  • An atoms is made up of some particles.
  • The proton is positively charged and it is located in the nucleus of an atom.
  • The neutrons do not carry any charges and occupies the nucleus with protons.
  • Electrons are the negatively charged particles outside the nucleus.
  • The electron cloud is portion of an atom with greatest probability of finding an electron.

Answer:

Hi. Increased evaporation would be the greatest difference.

Explanation:

Have you ever had a drink in a mug with a lid? When you would remove the lid, all of the liquid on the lid is the liquid that would evaporate if there was no lid.
