What is the molarity of a solution that contains 5.0 moles of solute in 2.0 liters of solution? 1.0 M 2.5 M 1.5 M 0.4 M

Answers

Answer 1

Answer: The molarity of a solution is defined as the moles of solute over liters of solution. That means that M=5/2=2.5. Therefore the answer is 2.5M. I hope this helps. Let me know if anything is unclear.

A 25.5 liter balloon holding 3.5 moles of carbon dioxide leaks. How many grams of carbon dioxide escaped before the container could be sealed if the new volume of the balloon is 15.4L?

Answers

Assumptions made:
1. Temperature and pressure is constant.
2. Ideal gas is involved.

The variables involved in this problem is the moles of the gas and the volume. We find their relationship from the ideal gas law. PV=nRT. With all other concept besides n and V is constant, Volume is directly proportional to the amount of gas inside the balloon. Solving this is as simple as ratio and proportion.

25.5L/3.5 moles = =15.4L/X moles
X= 2.11 moles.

Answer:

61 grams

Explanation:

If the number of moles of CO₂ in the balloon is given to be 3.5 moles, the mass of CO₂ in the balloon will be

number of moles = mass ÷ molar mass

Hence, mass = number of moles × molar mass

Molar mass of CO₂ is 44g. This is 44 because the atomic mass of carbon is 12 while that of oxygen is 16. Thus, 12 + (16 × 2) = 44 g

mass= 3.5 moles × 44g

mass = 154g (which is the initial mass)

When the mass of CO₂ in the 25.5 liter balloon is 154g, the mass of CO₂ in the balloon when the volume of CO₂ in the balloon is 15.4 liter will be X

To get X,

25.5 L ⇒ 154g

15.4 L ⇒ X

cross-multiply, and

X = (15.4 × 154) ÷ 25.5

X = 93.00 grams (which is the final mass)

93.00 grams of CO₂ was left in the balloon, hence the mass of CO₂ that escaped will be: initial mass minus final mass

= 154g - 93g

= 61g

The mass of CO₂ that escaped is 61 grams

If the following elements were to combine with each other, choose which demonstrate the Law of Multiple Proportion. Select all that apply. Z:X = 7:1 A:Z = 2.5:1 A:Z = 2.2:1 Y:X = 11:1

Answers

Answer is: Z:X = 7:1 and Y:X = 11:1.

Law of multiple proportions or Dalton's Law said that the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.
In this example ratios are whole numbers, A:Z = 2.5 : 1 and A:Z = 2.2 : 1 are not whole number ratios.

Answer:

7.1 and 11.1

What’s is CO written?

Answers

Answer:

CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."

Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!
