Answer:
<h3>The answer is 0.79 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 2.56 g
volume = 3.25 mL
We have
We have the final answer as
<h3>0.79 g/mL</h3>
Hope this helps you
Answer:
7.22*10^24 molecules
Explanation:
Since one mole has 6.02*10^23 you'd multiply that number by 12
that equals 7.224*10^24 but you need sig figs

Answer:
Actual yield = 1.825 g
Explanation:
Given data:
Theoretical yield = 1.98 g
Percent yield = 92.1687%
Actual yield = ?
Solution:
Formula:
Percent yield = actual yield / theoretical yield × 100
Now we will put the values in formula:
92.1687 = actual yield / 1.98 g × 100
92.1687 / 100 = actual yield / 1.98 g
0.921687 = actual yield / 1.98 g
0.921687 × 1.98 g = actual yield
Actual yield = 1.825 g
Answer:
The maximum number of electrons present in a particular shell is calculated by the formula 2n^2. , where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)^2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2)^2 = 8 electrons.
