Please someone help me and yes it can be more then one answer but give me your best answer
Strike441 [17]

Answer:

????

Explanation:

None of those seem to be correct to me.

1. Observations are made using the five senses- sight, sound, touch, taste, and smell. So this is invalid.

2. Observations and experiments can both be done anywhere

3. See answer to 2

4. It's cut off? But observations can literally be as simple as looking at a stick and noting that it's brown, so from what I can read, it's invalid.

Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
9966 [12]
<h3>Answer:  C. a balance and a beaker</h3>

Explanation:

A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.

The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.

To get the density, you divide the mass over volume.

For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
