Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater? a cali
2 answers:
Answer:
A balance and a graduated cylinder.
Explanation:
<u><em>Density</em></u> is the relationship between mass and volume of a substance, the formula is:
ρ
Where m is the substance mass, and v is the volume.
If a student wants to measure the density of seawater, he or she should use a Balance, to measure the mass of the sample. And then use a Graduated cylinder, is a volumetric instrument that allows to contain liquids and then measures the exact volume of the sample.
Once the student obtains the mass and the volume, he/she has to replace the data in the density formula and so obtain the density of seawater.

Answer:
The answer is below
Explanation:
1) Equator: The equator is an imaginary line that divides the earth into two equal parts known as the northern hemisphere and southern hemisphere. The equator is a line of latitude.
Line A is the equator
2) Latitude: Latitude are imaginary lines on earth that run from the east to west.
Line B are lines of latitude
3) Longitude: Longitude are imaginary lines on earth that run from the north to south.
Line F is a line of longitude
4) Prime Meridian: The prime meridian is a 0° line of longitude. It serves as a reference for other lines of longitude measurement.
Line E is a prime meridian.
5) South pole: The south pole is at a latitude of 90°S and all the lines of longitude meet there.
Point D is the south pole
6) North pole: The north pole is at a latitude of 90°N and all the lines of longitude meet there.
Point C is the south pole
