16 g/ml
<h3>Further explanation</h3>
Given
mass = 32.40 g
volume = 2.0mL
Required
Density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 32.40 g / 2.0 ml
ρ = 16.2 g/ml
Rules for division: The least number of significant figures in the problem determines the number of significant figures in the answer.
32.40 = 4 sig.fig
2.0 = 2 sig fig
The answer must be 2 sig fig
So the answer = 16 g/ml

Explanation:
1. First take the cylinder volume formula:
2. Then take the values for the radius and the height of the cylinder and replace them into the formula:
3. Solve the equation:
Answer:
The answer to your question is: letter C
Explanation:
a. the sharing of electrons between a hydrogen atom and another atom. This description is not for hydrogen bonding, in hydrogen bonding atoms do not share electrons, to form this bond.
b. the electrostatic interaction between an atom that has lost an electron and an atom that has gained an electron. This definition is describing an ionic bonding, not a hydrogen bonding.
c. the interaction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. This is the right definition of hydrogen bonding, because is mentioning the interaction between a hydrogen and an electronegative atom.
Answer:
what is wright there is no question
