Answer:

$\boxed {\tt d\approx 2.7 \ g/cm^3}$

Explanation:

Density can be found by dividing the mass by the volume.

$d=\frac{m}{v}$

The mass of the marble slab is 4.24 kilograms.

The density is 1564 cubic centimeters.

Since we want to find the density, in g/cm^3, we must convert kilograms to grams. There are 1000 grams in 1 kilogram, so multiply 4.24 by 1000.

1000 g= 1 kg

4.24*1000=4240 grams

Therefore,

$m= 4240 \ g \\v= 1564 \ cm^3$

Substitute the values into the formula.

$d=\frac{4240 \ g}{1564 \ cm^3}$

Divide.

$d= 2.71099744 \ g/cm^3$

Round to the nearest tenth. The 1 in the hundredth place tells us to leave the tenth place as is.

$d \approx 2.7 \ g/cm^3$

The density is about 2.7 grams per cubic centimeter.

Draw the product formed when 2-butanol undergoes reaction with TsCl and Et3N. CH3C6H4SO2Cl.

Pie

Answer:

Explanation:

In organic chemistry, the reaction between 2-butanol with TsCl and Et3N is known as the tosylation of the alcohol hydroxyl group. Alcohol is being changed to tosylate by the use of tosyl chloride under the influence of a base. Tosylation of alcohol is an example of a nucleophilic substitution reaction. From the image attached below, we will see how the reaction between 2-butanol proceed into the product by using tosyl chloride and a base(Et3N).
