1 answer:

6 0

According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.

What is the number of moles of solute in 250 mL of a 0.4 M solution ?

Levart [38]

.4 M means that in 1 Liter of solution there are .4 moles.

Molarity x Liters = Moles

We have molarity, so convert mL to liters

250 mL x 1000mL/1 Liter = .25 L

Now, set up the equation

.4 M x .25 L = .1 moles of solute

A big difference is that for the Greeks philosophy was almost a fresh start. For us, doing philosophy cannot avoid taking into consideration what the great thinkers of the past have thought (or how they have thought).

Acetone (nail polish remover) has a density of 0.7857 g >cm3.

Stella [2.4K]

If acetone has a density of 0.7857 $\frac{g}{cm^{3} }$ the mass in grams of point A is 22.4 g and the volume at point B is 8.32 mL.

<h3>What is acetone?</h3>

Acetone is known as a chemical substance that is usually found in the environment but can also be produced artificially. Acetone is a polar organic product that interacts very well with water molecules, generating dipole-dipole relationships.It is colorless with a distinctive smell and taste, we find it in products known as <u>cleaning and personal care products</u>, but we can also use it as a solvent for substances.

Also in the environment in <u>plants, trees and in volcano emissions or in forest fires</u>, it does not become <em>toxic</em> in low doses but if it is exposed to an individual in high doses it can become <em>fatal</em>.

In the statement we can find that acetone has a density of 0.7857 $\frac{g}{cm^{3} }$ .

Therefore, we can confirm that if acetone has a density of 0.7857 $\frac{g}{cm^{3} }$ the mass in grams of point A is 22.4 g and the volume at point B is 8.32 mL.
