What is the volume of the granite piece in cubic centimeters

Hi there!

Your correct answer will be 12.2 cm³.

This is how you get there:

1 mL = 1 cm³

With this one conversion factor, you can extrapolate the final answer. When you add the granite to the water, which is filled to 25.0 mL, the water level then moves to 37.2 mL. If you subtract the before volume from the volume after, you will get an answer of 12.2 mL. Then use the conversion factor and, voila! 12.2 cm³

I hope this helps!

Which do you think would be safer for heating a flammable liquid sample contained in an open beaker, and Bunsen burner or an ele

Ray Of Light [21]

Answer:

Electric hot plate

Explanation:

Considering that the liquid sample is flammable, it wouldn’t be a good idea to have it near a source of fire which the Bunsen burner provides, rather it would be better to heat through an electric hot plate as its not near a source of flame and instead produces heat through electricity.

Which is an aspect of the kinetic-molecular theory and can be used to explain the compressibility of plasma

tekilochka [14]

The answer choice which represents an aspect of the kinetic-molecular theory and can be used to explain compressibility of plasma is; Particles move independently of one another and are widely spaced.

<h3>What is the kinetic-molecular theory?</h3>

The kinetic-molecular theory in discuss postulates about the states of matter.

Also, it is built upon the idea that matter is composed of tiny particles that are constantly in motion.

Hence, the theory is explanatory of the observable properties and behaviours of solids, liquids and gases and hence, explains the compressibility of plasma.

Remarks;

Particles move independently of one another and are widely spaced.
Particle kinetic energy increases with increasing temperature.
Particles exert no attractive or repulsive force on one another.
Particles always move even when they have fixed positions.

A solution is prepared by dissolving 15.0 g of NH3 in 250.0 g of water. The density of the resulting solution is 0.974 g/mL. The

iVinArrow [24]

Answer:

[NH₃] → 3.24 M

Explanation:

Our solute: Ammonia

Our solvent: Water

Solution's mass = Mass of solute + Mass of solvent

Solution's mass = 15 g + 250 g = 265g

We use density to determine, the volume.

D = mass /volume → Volume = m / D → 265 g /0.974 g/mL = 272.07 mL.

We convert the mL to L → 272.07 mL . 1L /1000mL = 0.27207 L

To determine molarity we need the moles of solute in 1 L of solution.

Moles of solute are: 15g / 17g/mol = 0.882 moles

[NH₃] = 0.882mol /0.27207 L → 3.24 M
