How many grams of the compound in the figure above are required to make 1 liter of a 0.5 M solution? (Note: The atomic masses, i

Dafna1 [17]

Answer:

This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.

The answer is: 30grams

Explanation:

According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M

Molarity or Molar concentration is calculated using the formula:

M= n/V

Where; M= Molarity (M) = 0.5M

n= number of moles (mol)

V= Volume (V) = 1L

Hence, number of moles (n) = M × V

n = 0.5 × 1

n = 0.5 moles.

To calculate the mass in grams of CH3COOH, we say;

Number of moles (n) × molar mass (MM)

Since atomic mass for (C= 12, H= 1 and O=16)

Molar mass of CH3COOH:

= 12 + 1(3) + 12 + 16 + 16 + 1

Molar mass of CH3COOH = 60g/mol

Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol

Mass = 30grams.

Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.

Turtles and leopards all have four limbs and an amnion. True The common ancestor of lamprey and lancelets had a vertebral column

kramer

Answer:

Explanation:

The objective is to conclude if the statements are true or false based on facts.

1) $\text{ Turtles and leopards all have four limbs and an amnion. }$ True

2) $\text{The common ancestor of lamprey and lancelets had a vertebral column. }$ False

This is because their ancestor is a Chordate who doesn't have a vertebral column but a notochord.

3) True

$\text{Frogs are the sister taxa of turtles and leopards because they are more }$

$\text{related to a common ancestor.}$

4) $\text{Leopards and bass are more closely related than turtles and bass}$ False

This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).

5) $\text{The taxon that shares the most recent common ancestor with frogs is the bass.}$ False

The taxa of turtles share a more common ancestor with frogs compared to bass.

6) $\text{Leopards and lancelets have no common ancestor. }$ False

The common distant ancestor for leopards and lancelets is known as Chordates

Compare what life would be like living with sickle cell anemia versus living with tay sachs disease

Fantom [35]

<span>If I didn't know I had tay sachs (a genetic neurodegenerative condition), I would be terrified because of what I would perceive as a dysfunction of my brain. Once I were diagnosed with it, I would know there isn't any cure or treatment. I'd know that it would cause me to have a range of issues, such as paralysis, seizures and dementia. All of these would absolutely diminish my quality of life, both physically and emotionally, and shorten it. On the other hand, the effects on me of sickle cell anemia (a red blood cell disorder) would be comparatively less severe. It is treatable and manageable through diet, exercise, medication and other measures. The main symptions are pain, swelling and fatigue. Although the quality of my life would be significantly altered, at least I would feel I had options to mitigate its effects.</span>
