Draw both the chair and boat conformation of 1,4-dimethylcyclohexane with the methyl groups as cis and trans for both conformati
andrezito [222]

Answer:

Boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.

Explanation:

From the conformations, the boat conformation cis 1,4-dimethyl cyclohexane is least stable due to the fact that two methyl groups are located in opposite direction to each other, this leads to the production of  a higher strain. Similarly, Chair conformations appear more stable than boat conformation. Hence, energy is inversely proportional to stability. As a result of the aforementioned, boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.

Calculate the molar mass of butane. Butane's rate of diffusion is 3.8 times slower than that of hleium.
Pie

Answer:

58 g/mol

Explanation:

According to Graham's law, the rate of diffusion of a gas (r) is inversely proportional to the square root of its molar mass (M). Butane's rate of diffusion is 3.8 times slower than that of helium, that is, rButane = rHe/3.8, or rHe/rButane = 3.8. Then,

\frac{rHe}{rButane} =3.8=\sqrt{\frac{M(Butane)}{M(He)} } =\sqrt{\frac{M(Butane)}{4.00g/mol} } \\M(Butane)=3.8^{2} \times 4.00g/mol\\M(Butane)=58g/mol

Mole Conversion: What is the mass of 5 moles of O3?​​
Inessa05 [86]

240g

Explanation:

Number of moles = 5

Molar Mass = 16 x 3 = 48

Number of moles = Mass/Molar Mass

Mass = Number of moles x Molar Mass

Mass = 5 x 48

Mass = 240g
