Answer:
The new volume of the balloon will be 6046.28 L
Explanation:
Initial pressure (P1) = 99 kpa
initial volume (V1) = 3000 L
Initial temperature = 39 C = 39 + 273 = 312 K
Final pressure (P2) = 45.5 kpa
Final temperature = 16 C = 16 +273 = 289K
Final volume = ????
To calculate the final volume using the general gas equation
P1 V1 / T1 = P2 V2 / T2
make V2 the subject of the formular
V2 = 99000 ×3000× 289 / 45500×312
V2 = 85833000 /14196
V2 = 6046.28 litres
What your going to do is take away the lowest number form the highest and subtract. Thats your answer...
Answer:
mass of kI = 74.55 Atomic mass
74.55 g ---> 1 mole
48.9 g --> ?
48.9 / 72
0.7 mole.
In one mole of kI --->
Answer:
They are called hydrocarbons
Answer:
1.Accuracy
2.Acceptance
Explanation:
1. The first advantage is Accuracy. Using meters gives us a far more precise unit of measurement because of the exact scale of reading whereas hands and steps are more of approximate methods as they may not be as accurate as the using meter due to lack of exact scale of reading.
2. The second advantage is Acceptance. Usage of meter as a unit of measurement of length is now a widely accepted unit of measurement whereas, hands and steps are not widely accepted due to their approximate nature as compared to the exact nature of metres.
