What is the mass of 1 mole of lithium?

Korolek [52]

Answer: The mass of 1 mole of lithium is 6.941 grams.

Explanation:

To calculate the mass of a compound or element, we use the formula used to calculate the number of moles:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Where,

Number of moles of lithium = 1 mole

Given mass of lithium = ? g

Molar mass of lithium = 6.941 g/mol

Putting value in above equation, we get:

$1mole=\frac{\text{Given mass}}{6.941g/mol}\\\\\text{Mass of lithium}=6.941g$

Hence, the mass of 1 mole of lithium is 6.941 grams.

If He gas has an average kinetic energy of 4310 J/mol under certain conditions, what is the root mean square speed of O2 gas mol

Free_Kalibri [48]

Answer:

The root mean square speed of O2 gas molecules is

519.01 m/s

Explanation:

The root mean square velocity :

$v_{rms}=\sqrt{\frac{3RT}{M}}$

$K.E_{avg}=\frac{3}{2}RT$

$K.E =\frac{1}{2}mv_{rms}^{2}$

Molar mass , M

For He = 4 g/mol

For O2 = 2 x 16 = 32 g/mol

O2 = 32/1000 = 0.032 Kg/mol

First calculate the temperature at which the K.E of He is 4310J/mol

K.E of He =

$K.E_{avg}=\frac{3}{2}RT$

$T=\frac{2(K.E)}{3(R)}$

K.E of He = 4310 J/mol

$T=\frac{2(4310J/mol)}{3(8.314J/Kmol)}$

$T=345.60K$

Now , Use Vrms to calculate the velocity of O2

$v_{rms}=\sqrt{\frac{3(8.314J/Kmol)(345.60K)}{0.032Kg/mol}}$

$v_{rms}=\sqrt{\frac{8619.9552}{0.032}}$

$v_{rms}=\sqrt{26935.001}$

$v_{rms}=519.01m/s$

Electronegativity is a measure of how easy it is for an atom to attract another electron. the elements he, ne, and ar have the l

ruslelena [56]

These atoms and other atoms in group 8A have constant valence shell.it means that all of them have 8 electrons in their valence shell (except helium that has only 2 electrons )and they don't want to attract electrons.
that s why they don't have electronegativity.
hope this helps
