Answer:
V₂ = 1.41 mL
Explanation:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Given data:
Initial volume = 21 mL
Initial pressure = 1 atm
Initial temperature = 10 °C (10 +273 = 283 K)
Final temperature = 12 °C (12 +273 = 285 K)
Final volume = ?
Final pressure = 15 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁T₂/T₁ P₂
V₂ = 1 atm × 21 mL × 285 K / 283 K × 15 atm
V₂ = 5985 atm .mL. K / 4245 K. atm
V₂ = 1.41 mL
Density=mass/volume
Density= 4 g/2 mL/cm3
Density =2 g/cm3
Answer: i honestly dont know that is like what 9th grade science im only a 6th grader lol
Explanation: none
