The answer to this question is: The pressure will be increased two times
The gas law includes an interaction of pressure(p), volume(V) and temperature(T). In this case, the gas has same amount and volume but then the temperature is doubled. The calculation would be:
p1 * V1 / T1= p2*V2 /T2
p1 * 1 / 1 = p2 * 1 / 2
p1 / (1/2)=p2
p2= 2* p1
Answer:
5000 mL
Explanation:
Given data:
Volume in mL of solution = ?
Molarity of solution = 0.500 M
Number of moles of sugar = 2.5 mol
Solution:
Molarity = number of moles of solute/ volume of solution L
Now we will put the values.
0.500 M = 2.5 mol / Volume in L
Volume in L = 2.5 mol / 0.500 M
Volume in L = 5 L (M = mol/L)
Volume in mL.
5 L × 1000 mL / 1 L
5000 mL
Answer:
Generally, observed behavior that can be formulated into a statement, sometimes mathematical in nature, is called a natural law- D.
Answer:
Variability of data around the mean is best expressed through the standard deviation.
Explanation:
We have some statistical metrics, and we need to find the best measure of the variability of data around the mean.
First variable is mode. Mode of a set of data values is the value that appears most often. It means the most frequent data.
Second variable is Median. The median is a simple measure of central tendency. It is located around 50% of data range.
Third variable is standard deviation. The standard deviation is found by taking the square root of the average of the squared deviations of the values subtracted from their average value. It means, it will show the dispersion of data around the average value.
According to the definition presents for the three variables, Standard deviation is the most appropriate measure of variability of data around the mean.
