The mass of 1 atom of copper metal in the given face-centered cubic structure is determined as 1.054 x 10⁻²² g.
<h3>
Mass of 1 atom of copper</h3>
The mass of 1 atom of copper is calculated as follows;
mass of 1 atom of copper = molar mass of copper / Avogadro's number
substitute the value of molar mass of copper and Avogadro's number;
mass of 1 atom of copper = (63.5 g/mol) / (6.023 x 10²³)
mass of 1 atom of copper = 1.054 x 10⁻²² g
Thus, the mass of 1 atom of copper is determined as 1.054 x 10⁻²² g.

Answer:
19
Explanation:
1240.64/64
This is a simple division that can easily be evaluated using any form of calculator.
Here, the main challenge is in expressing the answer in the proper number of significant figure.
The approach here is to express the answer to the which is least precise. This is usually the number with the lower significant values.
Here, 64 has two significant figures and it is of a lower rank. Our answer should be expressed this way:
= 19.385 = 19
Answer:
<h3>The answer is 7.14 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = final volume of water - initial volume of water
volume = 52.1 - 50.7 = 1.4 mL
We have
We have the final answer as
<h3>7.14 g/mL</h3>
