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

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%.

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for the correct calculation of velocity?A) the direction
B) the end point

Answers

Answer:

The direction is missing here.

Explanation:

It is given that,

Veronica's velocity, v = 4.3 m/s

Distance, d = 20 m

Time taken, t = 4.7 s

The velocity of an object is defined as the net displacement divided by total time taken.

We need to find the missing information. We know that velocity is a vector quantity i.e. it has both magnitude and direction. Here, only magnitude of velocity is given but the direction is missing. So, the correct option is (a) " the direction".
B) The end point

The direction is not really important.
