V1/T1 = V2/T2
V1= 3.5 L
T1 = 25 +273=298 K
T2 = 40.9 + 273 = 313.9 K
V2- ?
3.5 L/298 K= V2/ 313.9 K
V2 = (3.5 L*313.9 K)/298 K ≈ 3.69 L
Answer:
When you walk your dog, you are using energy from the sunlight to power the activity. Explain. The energy you use is transferred from glucose, which got it directly from sunlight.
Explanation:
Answer:
.46 moles
Explanation:
PV = n RT make sure you use the correct R = 8.31446 L-kPa/(K-mol)
36 * 38 = n * 8.31446 * (273.15 + 82)
n = .463 moles
Answer:
The jewelry is 2896.54_Kg/m^3 less dense than pure silver
Explanation:
Density of jewellery = (mass of jewellery) ÷ (volume of jewellery)
=3.25g ÷ 0.428mL = 0.00325Kg÷0.000000428m^3 = 7583.46Kg/m^3
The density of silver is 10490_Kg/m^3 which is (10490 - 7583.46) 2896.54_Kg/m^3 more dense than the jewellery
The density of Silver [Ag]
The weight of Silver per cubic centimeter is 10.49 grams or the weight of silver per cubic meter is 10490 kilograms, that is the density of silver is 10490 kg/m³; at 20°C (68°F or 293.15K) at a pressure of one atmospheres.
