Say you had another object of the exact same material as the previous question. You need to know the volume but the object is irregularly shaped and is much too large for graduated cylinder. However, you know that the mass is 382 g. What is the volume of the object?

Answers

Answer:

  • 152.8 cm3

Explanation:

We are given that the material of the object is the same as the previous object

In the previous question, we determined the density of the material is 2.5 g/cm3

We are given the mass of this object is 382 g

To find the volume, we can use the equation:

  • Mass = Density x Volume

Plugging in the values we know:

  • 382 g = (2.5 g/cm3) x Volume

Solving for Volume:

Volume = Mass / Density

  • = 382 g / 2.5 g/cm3
  • = 152.8 cm3

A solution contains 20.0 g of C6H12O6 (glucose) in 250 g. of water.A. what is freezing point depression of solvent?

Answers

Answer:

The freezing point depression of solvent is 0.8265 K.

Explanation:

Mass of glucose = 250 g

Mass of solvent = 20.0 g = 0.020 kg

Molal depression water constant of water,K_f = 1.86 K kg/mol

Molality of the solution = (20 g)/(180 g/mol* 0.250 kg)=0.4444 mol/kg

Normal freezing point of water = T=273 K

Freezing point of solution = T_f

\Delta T_f=T-T_f

\Delta T_f=K_f* molality=1.86 K kg/mol * 0.4444 mol/kg=0.8265 K

The freezing point depression of solvent is 0.8265 K.
Molar mass glucose = 180 g/mol

number of moles:

20 / 180 = 0.111 moles

Δ t f *  ( Kf) *( i ) * ( m )

250 g of water in Kg = 250 / 1000 = 0.25 kg

1.86 ºC/m *  0.111 / 0.25

1.86ºC/m * 0.444

= 0.82584ºC

Fp = 0ºC -  0.82584

Fp = - 0.82584ºC

hope this helps!

The ______ energy lost by the inward movement of nickel-iron within a differentiating molten planetary body would be converted first into _______ energy and then into ______ energy. a. momentum, thermal, gravitational b. gravitational, kinetic, thermal c. thermal, momentum, kinetic d. kinetic, thermal, gravitational

Answers

Answer:b. gravitational, kinetic, thermal

Explanation:

The above explains the mechanism of the core forming process on earth/planet.

It is believed that this process might has contributed significantly to a planet's early stages heating. The time when these core-forming event happened is thought to have been mainly completed very early when Earth was young . The type of this event rather than it being seen as a single catastrophic event, it is likely to have been as a result of contractions on the earth severally.

The addition of partially differentiated material from another giant impact the rate of this spasm , and it increases each time the planet's mass is to increased.

This is a little on the history of planetary evolution.
