Answer:

DJ Kool Herc is widely credited with kicking off the genre. His back-to-school parties in the 1970s were the incubator of his burgeoning idea, where he used his two record turntables to create loops, playing the same beat over again, and extending the instrumental portion of a song.

A cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet. how much water can the silo hold, in terms of π? ref

Anestetic [448]

The amount of water that the cylindrical shaped silo can hold is 324π ft³.

Given the data in the question;

Diameter of the cylindrical silo; $D = 18ft$

Radius; $r = \frac{D}{2} = \frac{18ft}{2} = 9ft$

Height of the silo; $h = 4ft$

Volume of the silo in terns of $\pi$ ; $V = \ ?$

<h3> Volume</h3>

The volume of a cylinder simply signfies the amount of space in, i.e the quanity of materials it can carry or hold.

The volume of a cylinder is expressed as;

$V = \pi r^2h$

To determine the amount of water the silo can hold, we substitute our given values into the expression above.

$V = \pi r^2h\\\\V = \pi * (9ft)^2 * 4ft\\\\V = \pi * 324ft^2\\\\V = 324\pi ft^2$

Option B) 324π ft³ is the correct answer.

Hence, the amount of water that the cylindrical shaped silo can hold is 324π ft³.

How many grams of sodium chloride must be added to make 400. ml of a 0. 600 m sodium chloride

raketka [301]

Taking into account the definition of molarity, 14.028 grams of sodium chloride must be added to make 400 mL of a 0.600 M sodium chloride.

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

$Molarity=\frac{number of moles}{volume}$

Molarity is expressed in units $\frac{moles}{liter}$ .

<h3>Moles of sodium chloride</h3>

In this case, you know:

Molarity= 0.600 M
number of moles= ?
volume= 400 mL= 0.400 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

$0.600 M=\frac{number of moles}{0.400 L}$

Solving:

number of moles= 0.600 M× 0.400 L

number of moles= 0.24 moles

<h3>Mass of sodium chloride</h3>

Being the molar mass of sodium chloride 58.45 $\frac{g}{mole}$ , that is the amount of mass that a substance contains in one mole, the mass of sodium chloride can be calculated as:
