Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have
We have the final answer as
<h3>3.31 g/mL</h3>
Hope this helps you
Answer:
an be found by determining the electronic configurations of elements. Thereafter the number of electrons in the outermost shell gives the total number of valence electrons in that element.
Since the atomic mass consists of protons and neutrons, that would be the answer.
Answer: <span>C. the atomic mass </span>
Answer:
I am pretty sure that it is C
Explanation:
Answer:
The correct answer is 16.6 mL
Explanation:
The density of a substance is defined as its mass per unit of volume. Thus:
density = mass/volume
So, to calculate volume: volume = mass/density
Given:
density= 10.5 g/cm³
mass= 5.25 g
We calculate the volume occupied by silver as follows:
volume= mass/density= (5.25 g)/(10.5 g/cm³)= 0.5 cm³
Moreover, we know that 1 cm³= 1 ml. So, a mass of 5.25 g of pure silver occupies a volume of 0.5 ml. If we add the mass of silver to a graduated cylinder with 16.1 mL of water, the final volume will be given by the initial volume of water plus the volume occupied by silver:
volume level = 16.1 mL + 0.5 mL = 16.6 mL
