Answer:

<h3>The answer is 0.045 kg/cm³</h3>

Explanation:

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

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

From the question

mass of cylinder = 14 kg

Volume of a cylinder = πr²h

where

r is the radius

h is the height

radius =  \frac{diameter}{2}  \\

From the question

h = 25 cm

r =  \frac{4}{2}  = 2 \:  \:  \: cm

The volume of the cylinder is

V =  {2}^{2} (25)\pi \\  = 4 \times 25\pi \\  = 100\pi \\  = 314.159265...

We have

volume = 314.159 cm³

The density of the cylinder is

density =  \frac{14}{314.159}  \\  = 0.044563421...

We have the final answer as

<h3>0.045 kg/cm³</h3>

Hope this helps you

mezya [45]

Answer:

C. 3.40 ppm, singlet

Explanation:

Given the information from the question .we have to select the best representation for represents the predicted approximate chemical shift and coupling for hydrogen(s). In this case, there is no neighboring hydrogen .Thus there won’t be any split .the best option answer is C. 3.40 ppm, singlet . Therefore the correct answer or option is C. 3.40 ppm, singlet.

Help please chemistry will give brainliest
Jlenok [28]

Answer:

Explanation:

The Ideal Gas Law states that PV=nRT.

Rearrange that into P/n=RT/V.

In this case, the cylinder is rigid so the volume, V, does not change.

Temperature does not change either.

Out of 450 grams of gas, 150 grams leak out. So only 450-150 = 300 grams is left.

n is number of moles which is dependent on mass:

n1/n2 = 450/300 = 3/2

P1/n1 = RT/V = P2/n2

P2 = P1/n1*n2

= 7.2/3*2

= 4.8 atmosphere
