Anit [1.1K]

Answer:

48

Step-by-step explanation:

You are solving for the mean of the data set. To do so, add all the numbers together, and <em>divide by the amount of numbers in the set</em>.

Note that there are 4 numbers given to you: 38, 40 , 53, 61.

First, add the 4 numbers together:

38 + 40 + 53 + 61 = 192

Next, divide 4 from the total gotten:

192/4 = 48

48 is the mean of the data set.

The volume of 400 mL of chlorine gas at 400 mm Hg is decreased to 200 mL at constant temperature. What is the new gas pressure?
rusak2 [61]

A. Let us first assume that the gas acts like an ideal gas so that we can use the ideal gas equation:

PV = nRT

where P is pressure, V is volume, n is number of moles, R is universal gas constant and T is absolute temperature

In this case, let us assume that nRT = constant so that:

P1V1 = P2V2

400 mm Hg * 400 mL = P2 * 200 mL

P2 = 800 mm Hg

 

<span>B. The collision of gas with the walls of the container produces Pressure.</span>

It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?
4vir4ik [10]
220pm=10w  (people*minutes)

w=22pm

14w=308pm

308pm/14p=22m

So it would take 22 minutes for 14 people to paint 14 walls.
