In the world of chemistry a mole is a number of something a very large number of something.Just as a dozen is 12 of something a mole is about 6.0210^23 of something.
In chemistry we like the number of atoms or molecules in moles.
If one mole is equal to 6.0210^23 atoms and you have 9.00 *10^23 atoms then how many moles do you have?

Answers

Answer 1

Answer:

Answer;

= 1.495 moles

Explanation;

-One mole contains 6.02 ×10^23 particles

Therefore;

1 mole = 6.02 ×10^23 atoms

Thus; 9.00 ×10^23 atoms will have;

= 9.00 ×10^23 atoms / 6.02 ×10^23 atoms

= 1.495 moles

Answer 2

Answer:

Answer:

2.49

⋅

−

moles Pb

Explanation:

Before doing any calculations, it's worth noting that atoms do not contain moles, it's the other way around.

A mole is simply a collection of atoms. More specifically, you need to have exactly

6.022

⋅

atoms of an element in order to have one mole of that element - this is known as Avogadro's number.

In your case, you must determine how many moles of lead would contain

1.50

⋅

atoms of lead.

Well, if you know that one mole of lead must contain

6.022

⋅

atoms of lead, it follows that you get

1.50

⋅

atoms of lead in

1.50

⋅

atoms of Pb

⋅

1 mole Pb

6.022

⋅

atoms of Pb

2.49

−

Answers

The independent variable is the one that does not change depending on other variables - so here it would be the presence or the absence of caffeine - this is dependent on Tina's actions, but not on other variables in the experiment. The dependent variable is the heart rate - it is assumed to depend on the presence or absence of caffeine. A hypothesis could be that "Caffeine causes an increase of heart rate in earthworms" - and this hypothesis is what the experiment is testing.

___wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.a. solid
b. hazardous
c. domestic

Answers

Answer: Option (b) is the correct answer.

Explanation:

When a substance is used and thrown away which can lead to damage in the environment as it may [produce some toxic or hazardous gases is known as a hazardous waste.

These wastes can be solid, liquid or gaseous.

For example, batteries, kerosene, garden chemicals etc are all hazardous waste.

A domestic waste is a waste thrown by a household which may include paper, vegetable waste, cardboard, yard clippings etc.

Thus, we can conclude that hazardous wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.

Which of the following is not a colligative property of a solution?a. boiling point elevation
b. density
c. vapor pressure lowering
d. freezing point depression

Answers

The correct answer is (b.) density. Colligative properties are more concerned about the ratio between the number of particles of the solute and solvent in rather than the type of chemical or element present. Since boiling point elevation, vapor and osmotic pressure lowering and freezing point depression are considered as one of the colligative properties, it is definitely the density that does not belong to the group.

Answer:

B. Density
