Answer:
19.278049929737628457607385688801
Explanation:
Volume = L * W * H
Volume = 17.78 * 9.21 * 4.45 = 728.70441
Density = Mass / Volume
Mass = 14,048
14,048 / 728.70441 = 19.278049929737628457607385688801
Density = 19.278049929737628457607385688801
Then the new pressure of the sample of nitrogen is 1.28 atm
So, option D is correct one.
Calculation,
Formula used : (i)
Where , P is pressure and V is the volume
Given data,
= 3. 65 atm
= 21. 2 L
=
= 62. 6 L
= 22°C = 22+273 = 295 K
= 34°C = 34 +273 = 307 K
Putting the value of all data given in equation (i) we get,
3. 65 atm × 21. 2 L/295 K = × 62. 6 L / 307 K
= 3. 65 atm × 21. 2 L × 307 K/295 K × 62. 6 L = 1.28 atm
Then the new pressure the sample of nitrogen is 1.28 atm

The slope of a velocity-time graphs represents acceleration.
Answer: velocity-time.
Answer:
The amount of ampicillin stock is
The amount of deionized is 22.5 \ mL
Explanation:
From the question we are told that
The volume of stock solution of ampicillin in de-ionized water is
The concentration (in mg ) of ampicillin in de-ionized is
The volume of ampicillin in deionized water to produce is
The concentration (in mg ) of ampicillin in de-ionized water to produce is
The chemical process can be mathematically represented as
=>
The amount of ampicillin stock is and amount of 25 mL (30 - 7.5 = 22.5 mL ) of deionized water
C) the process by which individuals better adapted to their environment are most likely to survive and reproduce
