A 51.24-g sample of Ba(OH)2 is dissolved in enough water to make 1.20 liters of solution. How many mL of this solution must be d
g100num [7]

Answer:

0.40 L

Explanation:

Calculation of the moles of Ba(OH)_2 as:-

Mass = 51.24 g

Molar mass of Ba(OH)_2 = 171.34 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{51.24\ g}{171.34\ g/mol}

Moles= 0.2991\ mol

Volume = 1.20 L

The expression for the molarity is:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity=\frac{0.2991\ mol}{1.20\ L}=0.24925\ M

Thus,

Considering

Molarity_{working\ solution}\times Volume_{working\ solution}=Molarity_{stock\ solution}\times Volume_{stock\ solution}

Given  that:

Molarity_{working\ solution}=0.100\ M

Volume_{working\ solution}=1\ L

Volume_{stock\ solution}=?

Molarity_{stock\ solution}=0.24925\ M

So,  

0.100\ M\times 1\ L=0.24925\ M\times Volume_{stock\ solution}

Volume_{stock\ solution}=\frac{0.100\times 1}{0.24925}\ L=0.40\ L

<u>The volume of 0.24925M stock solution added = 0.40 L </u>

Compare and contrast the functions of each of the following types of flasks: filter, Erlenmeyer, volumetric. (Site 2)
gogolik [260]

Filter flasks are also known as vacuum, suction or the Buchner flasks. They have thick walls and also have a short glass tube. The thick walls are designed to enable the filter withstand high pressures of vacuum applied to filter substances. Generally this is used for filtering.

While the Erlenmeyer flask also called as a conical flask, is a titration flask which consists of a conical body, a flat bottom, and round neck. This is used for used for general uses such as mixing, titrations, preparation of cultures, for recrystallization, and for supporting filter funnels.

<span>Lastly, the Volumetric flasks are graduated flasks which having markings for different volumes. They are calibrated accurately for a specific amount of liquid that can be contained in it hence this is specially used for storing precise amounts of liquid. </span>

A student jumps of a sled toward the west after it stops at the bottom of an icy hill. Based on the law of action-reaction, in w
Delicious77 [7]

Answer:

East

Explanation:

Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.

This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.
