If 35.8 grams of LiCl are dissolved in 184 grams of water, what is the concentration of the solution in percent by mass?

Answers

Answer 1
Answer: Mass of solute = 35 grams
Mass of solution = mass of nacl + mass of water = 35.8 + 184 = 219.8 grams


Concentration = mass of Nacl x 100/mass of solution.

= 35x100/219.8 = 15.92%.

Hope this helps you.

Lee conducts an experiment to see if mass is conserved when a piece of charcoal is burned for 5.0 minutes. He measures the mass of the charcoal before lighting it with a match. At the end of 5.0 minutes, Lee puts out the fire by suffocating it. After the charcoal has cooled, he measures its mass again. His data are below.Initial Mass | Final Mass.415 | .289Charlene tries to repeat Lee's experiment by using a different piece of charcoal. But she burns the charcoal for just 3.0 minutes and collects all of the gas and dust released by the burning charcoal. She then weighs the total mass of these objects. Her results are below.Initial Mass | Final Mass.498 | .498Charlene's experimental results indicate that mass was conserved. Why do Lee's results indicate that mass was not conserved?He burned the charcoal for a longer period of time than Charlene did.He did not collect the gas and dust released by the burning charcoal.He forgot to measure the mass of the charcoal while it was still burning.Mass is not conserved when an object undergoes a chemical change.

Which describes the molecular behavior of a solid? I THINK IT'S A, BUT IM NOT SUREA. Molecules vibrate around a fixed point.
B. Molecules are too far apart to affect each other.
C. Molecules have the greatest energy of motion.
D. Molecules are rigid and do not move.

Answers

I also think it is A
Molecules in a solid should not be able to move. Otherwise it wouldn't be a solid! So the answer is D.

Amy is at basketball practice. She is about to shoot a free throw. When she releases the ball the ball will not have kinetic energy but will have potential energy. the ball will have kinetic energy but will not have potential energy. the ball will have kinetic energy and potential energy. the ball will have neither kinetic energy nor potential energy.

Answers

The ball will have kinetic energy because the released the potential and kinetic is taking over.

Answer:

The ball will have kinetic energy and potential energy

Explanation:

When Amy releases the ball, it will be moving. Therefore, it will have kinetic energy. But, because the ball will be in the air, it will also have gravitational potential energy. I also did the Study Island

Which group of elements is the most unreactive? Why?

Answers

Noble Gases because the valence electron shell, or orbital, is complete. They are "happy" with their electrons and don't need to react with others to change.

Explain whether nitrogen atoms will form bonds with other atoms

Answers

Nitrogen can also bond with otherthree atoms because of its outer shell (valence shell) that has three electrons.This is the reason why organic molecules can be so large because of thisbonding. Suppose you have a compound of NH3. You know that hydrogen can onlyshare 1 electron because 7 of its electrons are filled. Also, in nitrogen, it canonly share 3 electrons because 5 of it are already filled. That is why nitrogenneeds three hydrogen to form NH3.
