Explanation:
Answer: matter and its interaction with energy. Matter has mass and occupies space. A Substance is matter that cannot be separated into other kinds of matter by physical means.
Explanation:
Answer:
7.0 g/mL.
Explanation:
- Density is a characteristic property of a substance.
- The density of a substance is the relationship between the mass of the substance and the volume it takes up.
<em>d = m/V,</em>
where, d is the density of the metal,
m is the mass of the metal (m = 147 g),
V is the volume that the metal takes up (V = 41.0 mL - 20.0 mL = 21.0 mL).
<em>∴ d = m/V</em> = (147 g)/(21.0 mL) =<em> 7.0 g/mL.</em>
