Mass of the compound = 205 g
Molar Mass of compound = ((24) + (2 * 32) + (3 * 16))
= 136 g / mol
∴ # mols in 205g =
= 1.507 mol
Since 1.00 atm is equal to 760 mmHg, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm
<h3>What are the units of pressure?</h3>
Pressure is defined as the force acting perpendicularly per unit area of a surface.
The units of pressure include;
- millimetres of mercury, mmHg
- aatmospheres, atm,
- pascals, Pa
- Newtons per square metre, N/m^2
1 atmosphere is equal to 760 mmHg.
Therefore, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm

Answer:
This is based on the masses of one element, that will be combined with a fixed mass of the other element.
Explanation:
This is based on the masses of one element, that will be combined with a fixed mass of the other element. Thoses masses are in a ratio.
This state we can find in 'The Law of Multiple Proportions, which is part of Dalton's atomic theory
We see that in the 2 compounds, the masses of oxygen, that combine with a fixed mass of carbon , will be in proportion.
For the first oxide we have 1g carbon per 1.33 g Carbon
1g /1.33g = 0.752
For the second oxide we have 1g carbon per 2.66g Carbon
1g/2.66g = 0.376
Dividing the mass O per g C of the second (larger value) compound:
2.66 / 1.33 = 2 which is the same as 0.752 / 0.376
thus, it means that the masses of oxygen that combine with carbon are in a 2:1 ratio.
<span>star is born when clouds of dust and elements are gathered together in a certain space due to gravity, more and more mass and therefore pressure builds. when the pressure becomes enough to overcome the electronic repulsive force between two hydrogen nuclei, they are forced together and massive amounts of energy are given off forming helium atoms. this energy is then used to fuse other nuclei together. this could be compared to the way human life starts, where instead of 2 nuclei joining together to start a life cycle, two gametes, or sex cells are joined together. </span>
The Answer Is D: 2,4,& 6 .
