Answer:
V ∝ abc
Explanation:
This task is a joint variation task involving only direct proportionality:
Direct variation is one in which two variables are in direct proportionality to each other. This means that as one increases, the other variable also increases and vice - versa.
Joint variation is one in which one variable is dependent on two or more variables and varies directly as each of them.
In this exercise:
If a ∝ b and a ∝ c, then a ∝ bc
Taking the above three proportionalities,
V ∝ a ∝ b ∝ c
V ∝ a ∝ bc
V ∝ abc
This answer is D) none of these

Answer:
How many atoms are in 6.2 moles of aluminum? I mol = 6.02X1023 atoms so 6.2 mol = 6.2x (6.02x1025) = 3.73 x1024 atoms of Aluminum
