Answer:
<h3>The answer is 0.002 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass of sphere = 4000 g
Volume of a sphere is given by
![V = \frac{4}{3} \pi {r}^{3} \\](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%5C%5C%20)
where r is the radius
![r = \frac{diameter}{2} \\](https://tex.z-dn.net/?f=r%20%3D%20%20%5Cfrac%7Bdiameter%7D%7B2%7D%20%20%5C%5C%20)
From the question
diameter = 150 cm
![r = \frac{150}{2} = 75 \: \: \: cm](https://tex.z-dn.net/?f=r%20%3D%20%20%5Cfrac%7B150%7D%7B2%7D%20%20%3D%2075%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20cm)
The volume of the sphere is
![V = \frac{4}{3} \times {75}^{3} \pi \\ = \frac{4}{3} \times 421875\pi \\ = 562500\pi \\ = 1767145.86...](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes%20%20%7B75%7D%5E%7B3%7D%20%5Cpi%20%5C%5C%20%20%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%20%5Ctimes%20421875%5Cpi%20%5C%5C%20%20%3D%20562500%5Cpi%20%5C%5C%20%20%3D%201767145.86...)
We have the answer as
volume = 1767145.86 cm³
So we have
![density = \frac{4000}{1767145.86} \\ = 0.002263536...](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B4000%7D%7B1767145.86%7D%20%20%5C%5C%20%20%3D%200.002263536...)
We have the final answer as
<h3>0.002 g/cm³</h3>

<u>Answer:</u> The density of sugar is ![1.58g/cm^3](https://tex.z-dn.net/?f=1.58g%2Fcm%5E3)
<u>Explanation:</u>
To calculate the density of a substance, we use the equation:
![Density=\frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%3D%5Cfrac%7BMass%7D%7BVolume%7D)
We are given:
Mass of sugar = 316 g
Volume of box = ![200cm^3](https://tex.z-dn.net/?f=200cm%5E3)
Putting values in above equation, we get:
![\text{Density of sugar}=\frac{316g}{200cm^3}\\\\\text{Density of sugar}=1.58g/cm^3](https://tex.z-dn.net/?f=%5Ctext%7BDensity%20of%20sugar%7D%3D%5Cfrac%7B316g%7D%7B200cm%5E3%7D%5C%5C%5C%5C%5Ctext%7BDensity%20of%20sugar%7D%3D1.58g%2Fcm%5E3)
Hence, the density of sugar is ![1.58g/cm^3](https://tex.z-dn.net/?f=1.58g%2Fcm%5E3)
The oxidizing agent are the substance that is reduced because it gains electrons.
<h3>What is an oxidizing agent?</h3>
An oxidizing agent is defined as the agent that is capable of undergoing oxidation reaction by losing an electron.
The following are the characteristics of an oxidizing agent:
- At the end of the chemical reaction they are reduced,
- They gain electrons during chemical reaction.
- They can easily transfer their oxygen atoms.
