The mass of a substance is 27.46 g and its volume is 3.42 mL. What is the density of the substance? (hint: density = mass ÷ volu
marin [14]

Answer:

<h2>8.03 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{27.46}{3.42}  \\  = 8.029239

We have the final answer

<h3>8.03 g/mL</h3>

Hope this helps you

A substance that cannot be separated into simpler substances by physical or chemical means is a
Montano1993 [528]
Pure Substance- Element

Explanation:

Pure Substance VS. Mixture:
A pure Substance CANNOT be separated by physical changes, but a Mixture can.

PURE SUBSTANCE: Element VS. Compound:
An Element is one simple atom while a compound is two or more.
Example: Al (Aluminum) is an Element. CaCl (Calcium Chloride) is a compound.
You can split a compound with chemical changes because if you were to take the example, it would be a Calcium atom and a Chlorine atom.
You CANNOT split a single atom (Element) unless you want to make an atomic bomb which takes a lot of energy and you don’t want to destroy the whole world.

MIXTURE: Homogeneous VS. Heterogeneous:

Homo- mixed; cannot differentiate pieces
Hetero- can differentiate pieces
EX: homo- ketchup (can you see the difference in the vinegar and tomato paste? No)
Hetero- chicken noodle soup (there’s broth, chicken, peas, carrots, and other things)

A 15.0 kg chunk of ice falls off the top of an iceberg. If the chunk of ice falls 8.00m to to the surface of the water, what is
yulyashka [42]
When we can get the Kinetic energy from this formula KE= 1/2 M V^2
and we can get the potential energy from this formula PE =  M g H

we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so,
KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force and H is the height of the fall.
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s
