The atomic mass is defined as the mass an atom of an element. The atomic mass in approximation is equal to the sum of number of neutrons and protons in the nucleus of an atom (mass number). The units which are used for measuring the atomic mass is atomic mass unit, 
.
Thus, the correct option is option E that is atomic mass unit is used for measuring atomic mass.

Answer:
V₂ = 520.42 mL
Explanation:
Given data:
Initial volume = 350.0 mL
Initial pressure = 840 mmHg
Initial temperature = 33°C (33 +273 = 306 K)
Final temperature = 52°C (52+273 = 325 K)
Final volume = ?
Final pressure = 600 mmHg
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 840 mmHg × 350.0 mL × 325 K / 306 K × 600 mmHg
V₂ = 95550000 mmHg.mL.K /183600 K.mmHg
V₂ = 520.42 mL
Answer:
Well there are chemicals in the air like CO2 and nitrogen
Explanation:
These are chemicals and chemists deal with chemicals
Answer:
Final temperature = 25.71°C
Explanation:
By using formula Q=mcΔT
let's say x is final temperature
950 = 150.1 × 4.18 × ( x - 24.2 )
950 = 627.418 × ( x - 24.2)
950 = 627.418x - 15183.5156
627.418x - 15183.5156 = 950
627.418x = 950 + 15183.5156
627.418x = 16133.5156
x = 16133.5156 / 627.418
x = 25.71 °C
So...the final temperature is 25.71 °C
