Using the Charles law, the following are the solutions to the problems;
1) 16 dm3
2) 170 K
3) 2.4 L
<h3>What is Charles law?</h3>
Charles law states that, the volume of a given mass of gas is directly proportional to the temperature at constant pressure.
For problem 1;
T1 = 20 + 273 = 293 K
V1 = 15 dm3
T2 = 318 K
V2 = ?
V1/T1 = V2/T2
V1T2 =V2T1
V2 = V1T2/T1
V2 = 15 dm3 * 318 K/293 K
V2 = 16 dm3
Problem 2
V1 = 250cm3
T1 = 10 + 273 = 283 K
V2 = 150cm3
T2= ?
T2 = V2T1/ V1
T2 = 150cm3 * 283 K/250cm3
T2 = 170 K
Problem 3
V1 = 2.3 L
T1 = 25 + 273 = 298K
V2 = ?
T2 = 40 + 273 = 313 K
V2 = V1T2/T1
V2 = 2.3 L * 313 K/298K
V2 = 2.4 L

The longest side is from 6 to 30 and that means 6 was multiplied by 5 to get 30. The shortest side is 3 and multiply it by 5 and that’s 15
Answer: 10.6
Step-by-step explanation:
-7.1 + y = 3.5
y = 3.5 + 7.1 [ -7.1 changes to 7.1 when transferred to RHS]
y= 10.6

Answer:
Step-by-step explanation:
Hello!
a) The population of interest is the registered voters of the city of Raleigh.
b) This population is finite and its size is 10400 voters.
c) The sample was taken by making a telephone poll, calling 400 registered voters.
d) The sample size is n= 400 voters
The number of people that answered they'd vote for Brown are 151, so the sample proportion of voters that would vote for bron is:
p= 151/400= 0.3775 ≅ 0.38
e) To know how many people is expected to vote for Brown based on the results of the telephone poll you can do the following calculation:
10400*0.38= 3952
Based on the information obtained from the sample, it is expected that only 3952 voters will vote for Brown.
