Marina86 [1]2 years ago
8 0

Answer:

<h2>3,000,000 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{9 \times  {10}^{5} }{3 \times  {10}^{  - 1} }  \\

We have the final answer as

<h3>3,000,000 g/cm³</h3>

Hope this helps you

How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?
seraphim [82]
Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3

Phosgene is a highly toxic gas made up of carbon, oxygen, and chlorine atoms. Its density at 1.05 atm and 258C is 4.24 g/L. (a)
VikaD [51]

Answer:

Molar mass = 99 g/mol

Explanation:

Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2

The molar mass is given as the sum off the individual atomic mass of the elements in the compound.

Molar mass = C + O + 2Cl

Molar mass = 12 + 16 + 2(35.5)

Molar mass = 99 g/mol

Neptune's Triton is being pulled closer and closer to the planet as it orbits. What will likely be a result of this gravitationa
Ksenya-84 [330]

Answer:

the planet's gravity will cause Triton to fly into Neptune

Explanation:

Gravitational force is a force of attraction between two bodies with considerable masses.

One of the mass tends to pull the other to it's center.

As the force of gravity between two bodies grow, the more massive body will be drawn to the other one.

  • The effect is that one body will eventually collide with the other.
  • Since the planet pulls very hard on its moon
  • On the long run, we can expect Triton to fly into Neptune in the foreseeable future.

Use the data set to answer the question.
andrezito [222]

Answer:

It is both accurate and precise.

Explanation:

Precision and accuracy are two different terms used to describe data or measurements. Accuracy refers to how close a set of measurements/experimental values is to an accepted or correct value while Precision refers to how close a series of experimental values are to one another.

In the given set of data in the question below, the Correct Value is 59.2 while the experimental values are as follows;

Trial 1: 58.7

Trial 2: 59.3

Trial 3: 60.0

Trial 4: 58.9

Trial 5: 59.2

Based on comparison, it can be observed that these experimental values are close to the correct value (59.2). Hence, they are said to be ACCURATE. Also, the experimental values are close to one another, hence, they are said to be PRECISE.

Therefore, the data set is both accurate and precise.
