Answer:
d. 54.9 kPa
Explanation:
mmHg and Pa are units of pressure used in chemistry principally in the study of gases. 1mmHg is equal to 133.322Pa. 412mmHg are:
412 mmHg * (133.322Pa / 1mmHg) = 54929 Pa
The prefix K (Kilo) represents one thousand of the determined unit.
54929Pa are:
54929Pa * (1KPa / 1000Pa) = 54.9kPa
Right answer is:
<h3>d. 54.9 kPa

i think the answer is C3H8O
Like charges repel eachother. neutrons serve as a buffer so that the protons dont push each other apart
Since the question mentions a change in pressure from 1 atm to 6.73 atm, which triggers a change in volume, then it's premise is Boyle's Law, which notes that pressure is inversely proportional to volume (as volume decreases, pressure increases, and vice versa). As such, Boyle's Equation can be used to determine the initial pressure of the air. Also keen to note is that the Pressure at STP is 1 atm.
Boyle's Equation: P₁V₁ = P₂V₂
Since the initial pressure (P₁) is 1 atm, the final pressure (P₂) is 6.73 atm and the final volume is 995 mL, then we can substitute these into the equation to find the initial volume (V₁).
P₁V₁ = P₂V₂
∴ by substituting the known values,
⇒ (1 atm) (V₁ ) = (6.73 atm)(995 mL)
⇒ V₁ = (6,696.35 atm mL) ÷ ( 1 atm)
⇒ V₁ = 6,696.35 mL
<span>Thus, the original volume of this gas in mL is </span>≈ 6,696.35 mL
