Sugar is easily soluble in water and has a molar mass of 342.30 g/mol. What is the molar concentration of a 259.8 mL aqueous sol

DanielleElmas [232]

Answer:

$M=0.822M$

Explanation:

Hello,

In this case, given the mathematical definition of molar concentration as the moles of solute divided by the liters of solution:

$M=\frac{n}{V}$

We can easily compute it by firstly computing the moles of sugar by using its molar mass:

$n=73.1g*\frac{1mol}{342.30g} =0.214mol$

After that, we compute the concentration by realizing 259.8 mL equals 0.2598 L:

$M=\frac{0.214mol}{0.2598L}\\ \\M=0.822mol/L$

Or just:

$M=0.822M$

Considering molar units as mol/L

Best regards.

Why do compounds have different conductivity values if they are the same type of compound?

Karolina [17]

Compounds have different conductivity because if they have the same meaning it wont be a other word. the compounds have to have a conductivity so there can be more meanings.

A typical refrigerator is kept at 4˚C, and a soda can has a pressure of

ss7ja [257]

Answer: The new pressure will be 1.42 atm

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=1.18atm\\T_1=4^0C=(4+273)K=277K\\P_2=?\\T_2=60^0C=(60+273)K=333K$

Putting values in above equation, we get:

$\frac{1.18}{277}=\frac{P_2}{333}\\\\P_2=1.42$

Hence, the new pressure will be 1.42 atm

Why is the "coming up" list on the dashboard useful?

kirill115 [55]

I'm teaching with Canvas. On my dashboard, under the Coming Up section, none of the assignments that are on the calendar (populated b/c they are "assignments") are displaying. The next one is due in 36 hours so I think it should display and it is listed on the calendar.
