<u>Answer:</u> The amount of p-toluidine hydrochloride contained is 2.4 moles.
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
![\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%20of%20the%20solution%7D%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20solute%7D%5Ctimes%201000%7D%7B%5Ctext%7BVolume%20of%20solution%20%28in%20mL%29%7D%7D)
Molarity of p-toluidine hydrochloride solution = 0.167 M
Volume of solution = 70. mL
Putting values in equation 1, we get:
![0.167=\frac{\text{Moles of p-toluidine hydrochloride}\times 1000}{70}\\\\\text{Moles of p-toluidine hydrochloride}=\frac{(0.167\times 70}{1000}=2.38mol=2.4mol](https://tex.z-dn.net/?f=0.167%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20p-toluidine%20hydrochloride%7D%5Ctimes%201000%7D%7B70%7D%5C%5C%5C%5C%5Ctext%7BMoles%20of%20p-toluidine%20hydrochloride%7D%3D%5Cfrac%7B%280.167%5Ctimes%2070%7D%7B1000%7D%3D2.38mol%3D2.4mol)
Hence, the amount of p-toluidine hydrochloride contained is 2.4 moles.
Answer:
The carbon dioxide (CO2) emitted from power plants each year doesn't have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels.
Answer: NaNO3 (Sodium Trioxonitrate (V) )
Explanation:
The equation of the reaction is; HNO3 + NaOH -----> H2O + NaNO3
Yes thenpropert snd the negative end causes a iconic water fall
Chocolate milk is just regular white milk that has chocolate syrup/powder mixed into it
So no, chocolate milk does not come from brown cows
Hope this helps
