0.33g
Explanation:
Given parameters:
Diameter of cylinder = 0.234cm
length = 2.697cm
unknown:
mass of the cylinder = ?
Solution:
To solve this problem, we know that density of the aluminium can be determined and it is a constant.
Density is the mass per unit volume of a substance
Density = 
Mass of the cylinder = density x volume
To calculate the volume of cylinder;
Volume = π r² h
radius of the cylinder = 
= 0.12cm
Volume = 3.142 x 0.12² x 2.697 = 0.12cm³
Density of aluminium = 2.7g/cm³
Mass of the cylinder = 0.12 x 2.7 = 0.33g

Structure of a-chloro-b-methylbutyric acid (2-chloro-3-methylbutyric acid is attached below.
The structure was drawn using following information.
1) First, the parent chain was identified. The parent chain is containing four carbon atoms, also, this chain belongs to carboxylic acid as the compound name ends with Butyric acid i.e. butyr (Butane) -ic acid (carboxylic acid).
2) Secondly, the positions of substituents were assigned by using the rule which sates that the numbering in carboxylic acid must satrt from the carbonyl carbon. Therefore, the carbon which is attached to carbonyl carbon is named as alpha (2nd position) and carbon next to alpha carbon is named as beta carbon (3rd position). Hence, we add chlorine atom on 2nd carbon next to carbonyl group and methyl group at 3rd carbon with respect to carbonyl carbon.
Answer: The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.
Answer:
Explanation:
Hello,
In this case, considering that the density is considered as the quotient of the mass and volume:
We can easily compute the mass by solving for it as follows:
Best regards.
