Using the molecular weight (258 g/mol) determine the amount of mmol of (3S)-2,2,- dibromo-3,4-dimethylpentane required.

Varvara68 [4.7K]

The question is incomplete, the complete question is;

With all of this data in hand, we can now set up our reaction. To begin we are going to use 0.7 g of (35)-2.2-dibromo-3,4-dimethylpentane. Question #7: Using the molecular weight (258 g/mol) determine the amount of mmol of (3S)-2,2,- dibromo-3,4-dimethylpentane required. Round to the tenths place

Answer:

2.70 mmols

Explanation:

Given that;

Mass of (3S)-2,2,- dibromo-3,4-dimethylpentane = 0.7 g

Molar mass of (3S)-2,2,- dibromo-3,4-dimethylpentane = 258 g/mol

From,

Number of moles = mass/molar mass

Number of moles of (3S)-2,2,- dibromo-3,4-dimethylpentane = 0.7g/258 g/mol = 2.7 ×10^-3 moles

Therefore;

Number of moles of (3S)-2,2,- dibromo-3,4-dimethylpentane = 2.70 mmols

Which of the following is false? Charged molecules are insoluble in water. Hydrophobic molecules tend to be nonpolar and hydroph

inysia [295]

Answer:

Number 1 is false

Explanation:

1.- Charged molecules are insoluble in water. The statement is false, charged molecules are soluble in water and this is the main characteristic of charged molecules.

2.- Hydrophobic molecules tend to be nonpolar and hydrophilic molecules tend to be polar. This is true, hydrophobic molecules are non polar and hydrophilic molecules are polar.

3.- Gasoline has partial positive and negative charges which allows it to dissolve in water. This is true, gasoline is soluble in water.

4.- NH3 dissolves in water because its molecules form hydrogen bonds with water. This is true, NH3 interact with water because they can form hydrogen bonds.

5.- Hydrophobic molecules prefer to interact with each other in an aqueous solution. Absolutely true, hydrophobic molecules interact among them and they isolate from the environment.

Jared is practicing for a golf tournament. His normal driver distance is 250 yards. He hits three balls with his driver, and the

Nutka1998 [239]

Answer:

His drives are neither precise not accurate

Explanation:

It is true that his drives are neither precise nor accurate.

Accuracy is the exactness of measurement. It is the closeness of measured values to the true values.

In this problem, the true value is 250 yards, the measured values are 190 yards, 195 yards and 187 yards.

We can conclude that these numbers are very far from the true values. By virtue of that, they are inaccurate.

Precision is the ability to reproduce a set of experimental values. It is the closeness of the measured values to one another.

Jared failed to replicate his measured values over the three trials and so, his readings are not precise.

Therefore, his measurements are both imprecise and inaccurate.
