An aqueous solution containing 17.5 g of an unknown molecular (nonelectrolyte) compound in 100.0 g of water has a freezing point
Sonbull [250]

Answer:

molar mass = 180.833 g/mol

Explanation:

  • mass sln = mass solute + mass solvent

∴  solute: unknown molecular (nonelectrolyte)

∴ solvent: water

∴ mass solute = 17.5 g

∴ mass solvent =  100.0 g = 0.1 Kg

⇒ mass sln = 117.5 g

freezing point:

  • ΔTc = - Kc×m

∴ ΔTc = -1.8 °C

∴ Kc H2O = 1.86 °C.Kg/mol

∴ m: molality (mol solute/Kg solvent)

⇒ m = ( - 1.8 °C)/( - 1.86 °C.Kg/mol)

⇒ m = 0.9677 mol solute/Kg solvent

  • molar mass (Mw) [=] g/mol

∴ mol solute = ( m )×(Kg solvent)

⇒ mol solute = ( 0.9677 mol/Kg) × ( 0.100 Kg H2O )

⇒ mol solute = 0.09677 mol

⇒ Mw solute = ( 17.5 g ) / ( 0.09677 mol )

⇒ Mw solute = 180.833 g/mol

A 13-gram rubber stopper is attached to a 0.93-meter
makkiz [27]
<h3>Answer:</h3>

The centripetal acceleration is 26.38 m/s²

<h3>Explanation:</h3>

We are given;

  • Mass of rubber stopper = 13 g
  • Length of the string(radius) = 0.93 m
  • Time for one revolution = 1.18 seconds

We are required to calculate the centripetal acceleration.

To get the centripetal acceleration is given by the formula;

Centripetal acc = V²/r

Where, V is the velocity and r is the radius.

Since time for 1 revolution is 1.18 seconds,

Then, V = 2πr/t, taking π to be 3.142 ( 1 revolution = 2πr)

Therefore;

Velocity = (2 × 3.142 × 0.93 m) ÷ 1.18 sec

             = 4.953 m/s

Thus;

Centripetal acceleration = (4.953 m/s)² ÷ 0.93 m

                                        = 26.38 m/s²

Hence, the centripetal acceleration is 26.38 m/s²

When Brian first sorted out his thoughts, he figured this was the first day after the crash and what did he think would happen n
Leya [2.2K]

It should be noted that when Brian first sorted out his thoughts, the first thing that he thought would happen next is that he would probably be rescued that day.

It should be noted that in Chapter 5 of Hatchet, Brian wakes up in the forest and then, he realized that he was desperately thirsty.

When Brian first sorted out his thoughts, he figured this was the first day after the crash and that he would probably be rescued that day. He believed that he was going to wither up and die if he doesn't get anything that he'll drink.

The role of pigments both in capturing light energy and in converting it to the chemical energy of ATP and NADPH.
Aleonysh [2.5K]

Answer:

The explanation of the processes in which pigments are involved (capturing light and forming ATP and NADPH) is given in the following paragraphs)

Explanation:

Pigments are molecules with the capacity of absorbing light. Each pigment captures light of a specific wavelength. Plants contain different types of pigments like chlorophylls, xanthophylls, carotenoids, and others.

Chloroplasts (organelles present in cells of plants), contain pigmants that absorb solar radiation, triggering a series of reactions collectively known as photosynthesis. When light incides on a pigment, an electron of this molecules is excitated, goes into another level of energy and starts to pass through a series of carrier molecules to finally to a final aceptor of electrons. During this transport, part of the energy contained in the electron is used to generates a hydrogen gradient that provides energy. As a result of these processes, a molecule that is called  NADP+ accepts two electrons and an hydrogen to form NADPH, while another molecule known as ADP captures  an atom of phosphorous and gives rise to ATP (through the action of a protein called ATP sintase)..
