4.0 % in mass per volume :
4.0 g ---------- 100 mL
1.2 g ---------- ( volume )
Volume = 1.2 x 100 / 4.0
Volume = 120 / 4.0
= 30 mL
hope this helps!
Answer:
The correct classification of the statement is all compounds.
Explanation:
- All matter is defined as something that entirely has weight and occupies some sought of space. That's why it can't be used to describe the above statement.
- All elements are defined as substances that have an equal number of protons. The atoms in an element contain an exact atomic number.
- All compounds can be defined as a formation that takes place when a variety of atoms are chemically combined. Hence, this explains the answer above.
- All pure substances mean that the substance is not mixed with anything at all. It's just by itself.

By achieving octet configuration, the diatomic elements become more stable compared to the single atom. Therefore, oxygen and hydrogen are diatomic.
