Removing salt from water will reduce it's density
Answer:
Explanation:
<u>1) Data:</u>
<em />
a) V = 75.0 liter
b) n = 15.82 mol
c) p = 546.8 kPa
d) T = ?
<u>2) Formula:</u>
- Ideal gas equation: pV = nRT
Where:
- n = number of moles
- V = volume
- p = absolute pressure
- T = absolute temperature
- R = Universal Gas constat: 8.314 kPa - liter / K-mol
<u>3) Solution:</u>
a) <u>Solve the equation for T</u>:
b) <u>Substitute and compute</u>:
- T = 546.8 kPa × 75.0 l iter / (15.82 mol × 8.314 kPa-liter/K-mol) = 312 K
(since the volume is expressed with 3 significant figures, the answer must show also 3 significant figures)
