Answer:
35,000,000,000 mL
Explanation:
You first multiply 35 times 1000.
35,000 L
Now you multiply 35,000 times 10^6
35,000,000,000 mL
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Explanation:
Answer:
46.004 g/mol
Explanation:
Scottish physicist Thomas Graham formulated a law known as Graham's law of effusion in 1848. He conducted an experiment and found the relationship between the rate of effusion of a gas and its molar mass as:
![r=\sqrt {\frac {1}{M}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%20%7B%5Cfrac%20%7B1%7D%7BM%7D%7D)
where,
r is the rate of effusion of a gas
M is the molar mass of the gas.
Also, r = v/t
And for two gases taking different t₁ and t₂ to effuse, the formula is:
![\frac {t_2}{t_1}=\sqrt {\frac {M_2}{M_1}}](https://tex.z-dn.net/?f=%5Cfrac%20%7Bt_2%7D%7Bt_1%7D%3D%5Csqrt%20%7B%5Cfrac%20%7BM_2%7D%7BM_1%7D%7D)
So,
For Neon :
= 8.61 minutes
= 20.1797 g/mol
For unkown gas:
= 13.0 minutes
= ? g/mol
![\frac {13.0}{8.61}=\sqrt {\frac {M_2}{20.1797}}](https://tex.z-dn.net/?f=%5Cfrac%20%7B13.0%7D%7B8.61%7D%3D%5Csqrt%20%7B%5Cfrac%20%7BM_2%7D%7B20.1797%7D%7D)
<u>Molar mass of unknown gas = 46.004 g/mol</u>
