0.5 litres contain 1.1 moles
therefore 1 litre will have= 1*1.1/0.5
molarity=2.2M

Answer:

The correct answer is 2.2 mol/L

Explanation:

Molarity of a solution is used to determine the concentration of that solution. It is mathematically expressed as

Molarity (M) = number of moles ÷ volume (in liters or dm³)

The unit for molarity is mol/L or mol/dm³ or M

From the question, number of moles is 1.1 moles and the volume is 0.5 liters.

Hence,

Molarity = 1.1 ÷ 0.5

Molarity = 2.2 mol/L

Suppose you have 4.0 L of helium in a flexible container (like a balloon) at a certain temperature and pressure. What will the v

AleksandrR [38]

Answer:

Volume of the helium will be 1.0L

Explanation:

To understand this question it is necessary to talk about 2 laws:

Charles's law that states: The volume of a given amount of gas held at constant pressure is directly proportional to absolute temperature.

Boyle's law that states: The volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.

Now, in the problem, if you have 4.0L of helium:

If the temperature is halved and the volume varies directly with temperature (Charles's law), the volume of helium will be 2.0L

Then, the pressure es doubled and as volume varies inversely with pressure (Boyle's law), the volume of helium will be halved, being 1.0L.

Thus, volume of the helium will be 1.0L

A truckload of apples weighs 2550 lbs. If 5 (exact) apples weigh 1250 g, how many apples are in the truck?

egoroff_w [7]

Answer:

There are 4,626 apples in the truck.

Explanation:

Mass of 5 apples = 1250

Mass of an apple = $\frac{1250 g}{5}=250 g$

Mass of apples in the truck = 2550 lbs

1 lbs = 453.592 g

$2550 lbs=2550\times 453.592 g$

Let the number of apples with mass of 2550 lbs be a.

$a\times 250 g=2550\times 453.592 g$

$a=\frac{2550\times 453.592 g}{250 g}=4,626.63$

4,626.63 ≈ 4,626

So, there are 4,626 apples in the truck.

Which statement explains why the bonds between nonmetals tend to be covalent? The bonds are found to be nondirectional. They hav

Alexandra [31]

Correct Answer: They have small differences in electronegativity (statement 3)
Reason:
The nature of chemical bond between atoms is primarily driven by the electronegativity difference between constituent atoms. If electronegativity difference between constituent atoms is significantly higher, ionic bond formation is preferred. On other hand, low difference in electronegativity values, favours formation of covalent bond.
