Help me!!!!!!!!!!!!!<br>what is the most important factor in determining climate
cestrela7 [59]

The correct answer is - latitude.

The latitude in many ways is the most important factor in determining the climate of a place. The reason for that is mostly the shape of the planet, which doesn't allow the Sun light to be equally distributed on all of its surface. The lower the latitude, the more direct and more concentrated the Sun light, thus the place will be warmer. The higher the latitude, the sharper the angle of the fall of the Sun light, thus more dispersed Sun light, which will result in a much colder climate.

A solution contains 3.95 g of carbon disulfide (CS2, molar mass = 76.13 g/mol) and 2.43 g of acetone ((CH3)2CO, molar mass = 58.
Feliz [49]

Answer:

The solution is not ideal and shows a positive deviation from Raoult’s law since Psolution (experimental) > Psolution (actual).

Explanation:

Number of moles of CS2 = 3.95g/76.13gmol-1 = 0.0519 moles

Number of moles of acetone = 2.43g/58.08gmol-1 = 0.0418 moles

Total number of moles = 0.0937 moles

Mole fraction of CS2 = 0.0519/0.0937 = 0.5538

Mole fraction of acetone = 0.0418/0.0937 = 0.4461

From Raoult’s law;

PCS2 = 0.5538 × 515 torr = 285.207 torr

Pacetone = 0.4461 × 332 torr = 148.1052 torr

Total pressure = 285.207 torr + 148.1052 torr = 433.3 torr
