Answer:

Explanation:
Hello,
In this case, by considering the given seminormal solution, we infer it is a 0.5-N solution which means that we can obtain the equivalent grams as shown below for the 55 cc (0.055 L) volume:

Next, since sodium carbonate has two sodium ions with a +1 oxidation state each, we can obtain the moles:

Finally, the mass is computed by using its molar mass (106 g/mol)

It provides evidence that each organism is related and similar in each way, leading to the conclusion of a common ancestor.<span />

Hey there!
D = m / V
0.775 = m / 50.0
m = 0.775 * 50.0
m = 38.75 g
