Answer:

There are 140.9 grams in 2.393*10²⁴ aotms of Cl.

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023*10²³ atoms are contained in 1 mole of the compound, 2.393*10²⁴ atoms are contained in how many moles?

$amount of moles=\frac{2.393*10^{24} *1 mole}{6.023*10^{23} }$

amount of moles= 3.973

If the molar mass of Cl is 35.453 $\frac{g}{mole}$ , then the amount of mass that contains 3.973 moles can be calculated as:

3.973 moles*35.453 $\frac{g}{mole}$ = 140.85 grams ≅ 140.9 grams

There are 140.9 grams in 2.393*10²⁴ aotms of Cl.

Sports trainers treat sprains and soreness with ethyl bromide. it is manufactured by reacting ethylene with hydrogen bromide:

OverLord2011 [107]

Trainers use this substance because the reaction of the product on the skin is an exothermic one. This produces a feeling of warmth and heat. Heating an injury like a sprain with warmth or heat increases blood flow to the area and promotes healing as the flow of blood carries the necessary substances for healing.

A sample of nitrogen gas is collected over water at a temperature of 23.0 C. What is the pressure of the nitrogen gas if atmosph

Whitepunk [10]

We first consider the gases that will be present in that sample.
First, there will be nitrogen, as stated. Second, there will also be water in the form of water vapor. For this, we need the vapor pressure of water at 23.0 °C, which is about 21.0 mmHg. Now, the sum of the vapor pressures of the gases will be equivalent to the total pressure. So the pressure of nitrogen gas is:
785 - 21
= 764 mmHg

In order to design an experiment, you need a ____ about the scientific question you are trying to answer. A. decision B. procedu

kolbaska11 [484]

The correct answer is option C, that is, hypothesis.

The hypothesis is the starting building block in the scientific method. It is also illustrated as an educated guess, based on previous observation and knowledge. A hypothesis refers to a recommended solution for an unexplained event, which does not fit into the present accepted scientific theory.

The fundamental concept of a hypothesis is that there is no pre-determined result. For a hypothesis to be considered as scientific hypothesis, it has to be something, which can be refuted or supported via carefully crafted observation or experimentation.

Pretty much, if I were going to separate small solid particles, I could use like a piece of paper. I used some type of piece of paper when I was trying to separate some particles during science.
