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.

Hi Geny!

Question - Describe the cell theory and the developments that led to the cell theory.

Answer:

There are 3 main components of cell theory:

Each and every organism is wither unicellular or multicellular.
The basic unit of life is the cell.
Cells are created from cells that had existed previously.

There were 3 scientists that made cell theory each of the 3 components of above were the 3 scientists.

Mathia Schleiden discovered that plants were made of mainly cells.
Rudolf Virchow discovered that cells are created from calls that had existed previously.
Theodore Schwann discovered that animals were also made of mainly cells.

Hope This Helps :)

The bicondylar angle positions the center of mass above the base of support during the single-support phase of bipedal locomotio

Reptile [31]

Answer:

The bicondylar angle positions the center of mass above the base of support during the single-support phase of bipedal locomotion.

A. True

Explanation:

The bicondylar angle is the functional angle between the diaphysis of the femur, perpendicular to the intercondylar plane. Very unique to humans, this angle places the knee and the foot under the body's center of gravity during a single support phase of locomotion or gait. With hip joints set lateral to the body's midline, the bicondylar angle aligns the lower limb with the center of gravity, thereby facilitating human movement.
