claim: density is a ratio of mass and volume. it can be used to identify unknown substances.
evidence:

	mass of liquid (g)	volume (ml)	density (g/ml³)	substance
liquid b	type answer	10 ml	type answer	type answer
liquid c	type answer	10 ml	type answer	type answer

reasoning: density is a __ of matter. it is calculated using a known and . mass is the amount of in something. is the amount of that a substance __.

Explanation:

Claim:

Density is a ratio of mass and volume. It can be used to identify unknown substances.

Reasoning:

Density is a property of matter. It is calculated using a known mass and volume. Mass is the amount of matter in something. Volume is the amount of space that a substance takes up.

For the Evidence Table (assuming we have actual mass values, here's how to calculate density):

The formula for density is $
ho = \frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume.

For Liquid A (example with a hypothetical mass, say 8 g):

Step 1: Identify mass and volume

Mass ($m$) = 8 g, Volume ($V$) = 10 mL

Step 2: Apply density formula

$
ho = \frac{8}{10} = 0.8$ g/mL
Then, based on density values, we can identify the substance (e.g., if density is 0.8 g/mL, it could be ethanol).

For Liquid B (example with a hypothetical mass, say 10 g):

Step 1: Identify mass and volume

Mass ($m$) = 10 g, Volume ($V$) = 10 mL

Step 2: Apply density formula

$
ho = \frac{10}{10} = 1$ g/mL (could be water)

For Liquid C (example with a hypothetical mass, say 12 g):

Step 1: Identify mass and volume

Mass ($m$) = 12 g, Volume ($V$) = 10 mL

Step 2: Apply density formula

$
ho = \frac{12}{10} = 1.2$ g/mL (could be a salt solution)

(Note: Actual substance identification would require comparing with known density values, and the mass values need to be measured experimentally to fill in the "Type answer" fields.)

Key Relationships Summary:

• Density = $\frac{\text{Mass}}{\text{Volume}}$ (a physical property of matter).
• Mass: Amount of matter in an object.
• Volume: Amount of space an object/substance occupies.
• Density helps identify unknown substances because each pure substance has a characteristic density.
