The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres. The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S hope this helps

What is the molarity of 225 mL solution containing 1.89g of K₂SO₃•8H₂O? * 2 points 3.77 x 10⁻³ M 6.44 x 10⁻¹ M 3.87 x 10⁻²M 2.78

SCORPION-xisa [38]

Answer:

2.78 x 10⁻² M

Explanation:

Step 1:

Data obtained from the question.

Volume = 225mL / 1000 = 0.225L

Mass of K₂SO₃•8H₂O = 1.89g

Molarity =..?

Step 2:

Determination of the number of mole of K₂SO₃•8H₂O

This is illustrated below:

Mass of K₂SO₃•8H₂O = 1.89g

Molar mass of K₂SO₃•8H₂O = (39x2) + 32 + (16x3) + 8[(2x1) + 16] = 78 + 32 + 48 + 8[18] = 302g/mol

Number of mole = Mass/Molar Mass

Number of mole of K₂SO₃•8H₂O = 1.89/302 = 6.26x10⁻² mole

Step 3:

Determination of the molarity.

Molarity = mole /Volume

Molarity = 6.26x10⁻² /0.225

Molarity = 2.78 x 10⁻² M

Therefore, the molarity of the solution is 2.78 x 10⁻² M

at what temperature would 250mL of water boils? 1000mL? is the boiling point an intensive or extensive property? explain.

Ierofanga [76]

Water always boils at 212 degrees F, or 100 degrees C. Because the boiling point is not dependent on the size of the sample of water, it would be an intensive property.

Which of the following conditions remain constant in Gay-Lussac's law? Temperature and number of moles Volume and number of mole

saw5 [17]

Answer:

Volume and number of moles.

Explanation:

Gay-Lussac's law was found by Joseph Louis Gay-Lussac in 1808.

It states that, for a given mass (no. of moles) and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

So, no. of moles and V are constant.

P ∝ T,

So, the right choice is: <em>Volume and number of moles.</em>
