Let's assume that the gas has ideal gas behavior.
Ideal gas law,<span>
PV = nRT
(1)
Where, P is the pressure of the gas (Pa), V is the volume of
the gas (m³), n is the number of moles of gas (mol), R is the
universal gas constant ( 8.314 J mol</span>⁻¹ K⁻<span>¹)
and T is temperature in Kelvin.
</span>n = m/M
(2)
Where, n is number of moles, m is mass and M is
molar mass.
From (1)
and (2),
PV = (m/M) RT
By
rearranging,
M =
(mRT)/PV (3)
P = standard pressure = 1 atm = 101325
pa
V = 0.896 L = 0.896 x 10⁻³ m³
R = 8.314 J mol⁻¹ K⁻¹<span>
T = Standard temperature = 273 K
m = </span>3.87 g = 3.87 x 10⁻³ kg<span>
M = ?
</span><span>
By appying the formula,
M =(</span>3.87 x 10⁻³ kg x 8.314 J mol⁻¹ K⁻¹ x 273 K) /101325 pa x 0.896 x 10⁻³m³
<span>M = 0.0967 kg
M = 96.7 g.
Hence, the molar mass of the gas is 96.7 g.

Hubble has aided scientists in their understanding of the solar system. Comets and planets are observed by the telescope.
Galaxies that were there when the cosmos was still only 600 million years old have been surveyed by Hubble. Galaxies were thought to have formed when the cosmos had existed for at least the two billion years. The photos from the equipment have aided research into the evolution of galaxies.
Even previously unseen moons surrounding Pluto were found by Hubble. Scientists' understanding of how planets as well as galaxies form has been aided by the telescope.
Therefore, Hubble has aided scientists in their understanding of the solar system. Comets and planets are observed by the telescope.

Answer:
Density is the ratio of the mass of an object to its volume. Density is an intensive property, meaning that it does not depend on the amount of material present in the sample. ... Since a cubic centimeter is equal to a milliliter, density units can also be expressed as g/mL.
Explanation:
Answer:
Use the Bromotriflouride catalyst, BF₃
Explanation:
The BF₃ is most likely to yield less desired side products. The effect lies in the reaction mechanism.
BF₃ is a Lewis acid. Its role is to promote the ionization of the HF. This is achieved through the electrophilic mechanism. The reaction mechanism is as follows:
2 - methylpropene + H-F-BF₃ → H-F + H₃C + benzene
butylbenzene + F-BF₃ → tert-butylbenzene + H-F + BF₃ (regenerated catalyst)
