How many grams of C8H18 is in 405,576.398 mL

$Molarity X \frac{0.762 mol}{05.576398 L} = Mass$ is the of $C_8H_1_8$ is in 405,576.398 mL.

<h3>What is molarity?</h3>

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.

Given data:

Molar mass of $C_8H_1_8$ = 0.762 mol

Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L

Solution:

Step 1: Calculating moles of $C_8H_1_8$

• Molarity = $\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}$

• Putting the value in the given formula

• Moles of solute C8H18 = $\frac{\;Mass}{\;Molar \;molar \;mass}$

• Moles of solute C8H18 = $\frac{\;Mass}{0.762 mol}$

Now,

Molarity = $\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}$

Molarity = $\frac{\frac{\;Mass}{0.762 mol}}{\;Volume \;of \;solution \;in \;litre}$

Molarity = $\frac{\frac{\;Mass}{0.762 mol}}{405.576398 L}$

$Molarity X \frac{0.762 mol}{05.576398 L} = Mass$

Hence, $Molarity X \frac{0.762 mol}{05.576398 L} = Mass$ is the of $C_8H_1_8$ is in 405,576.398 mL.

Enough of a monoprotic acid is dissolved in water to produce a 0.0121 M solution. The pH of the resulting solution is 6.49. Calc

Hitman42 [59]

Calculate the H positive from the pH equation: pH equals -log (H positive). This would be 10 to the -6.49. Let's call the acid HA. To calculate Ka in this equation, Ka equals H positive times A- over HA. HA is going to be the 0 0121. So, Ka=(10^-6.49)^2/0.0121. This equals 1.05*10^-13/0.0121. Ka then equals 8.65*10^-12.

Please help, thanks!

Anastasy [175]

You need to use the formula--> P1V1= P2V2 (Boyles's law)

P1= 14 bar
V1= 312 mL
P2= ?
V2= 652 mL

now we plug the values into the formula.

(14 x 312) = (P2x 652)

P2= (14 x 312)/ 652= 6.70 bar

Yeast converts glucose to ethanol and carbon dioxide during a process known as anaerobic fermentation. The chemical reaction is

Korolek [52]

Answer:

102g

Explanation:

To find the mass of ethanol formed, we first need to ensure that we have a balanced chemical equation. A balanced chemical equation is where the number of atoms of each element is the same on both sides of the equation (reactants and products). This is useful as only when a chemical equation is balanced, we can understand the relationship of the amount (moles) of reactant and products, or to put it simply, their relationship with one another.

In this case, the given equation is already balanced.

$\tex{C_6H_{12}O_6} \longrightarrow 2 \ C_2H_6O + 2 \ CO_2$

From the equation, the amount of ethanol produced is twice the amount of yeast present, or the same amount of carbon dioxide produced. Do note that amount refers to the number of moles here.

Mole= Mass ÷Mr

Mass= Mole ×Mr

Method 1: using the mass of glucose

Mr of glucose

= 6(12) +12(1) +6(16)

= 180

Moles of glucose reacted

= 200 ÷180

= $\frac{10}{9}$ mol
