Answer:
The outside temperature is -45.8°C
Explanation:
When a gas keeps on constant its moles and its pressure, we can assume that volume will be increased or decreased as the T° (absolute T° in K).
V1 / T1 = V2 / T2
2.95L/298K = 2.25L / T2
(2.95L/298K ) . T2 = 2.25L
T2 = 2.25L . 298K / 2.95L
T2 = 227.2K
T°K - 273 = T°C
227.2K - 273 = -45.8°C
Answer:
2.47 M
Explanation:
Molarity is (mol of solute)/(L of solvent). To find molarity, convert grams of NaCl to moles of NaCl and milliliters of water to liters of water.
72.3 g ÷ 58.44 g/mol = 1.2372... mol
500 mL ÷ 1000 mL = 0.5 L
Molarity = 1.2372/0.5 = 2.47 M
Answer:
17.1 L
Explanation:
P1V1/T1 = P2V2/T2 T is in K
P1V1/T1 * T2/P2 = V2
735 * 7.31 / (45+273.15) * (55+ 273.15)/325 = V2
V2 = 17.1 L
