<span>Colligative properties are properties of solutions that depend on the number of molecules [or ions] in a given volume of solvent and not on the properties (e.g. size or mass) of the compound. Colligative properties include: lowering of vapor pressure; elevation of boiling point; depression of freezing point and osmotic pressure.</span>
Volume of tank =

Since,
So,
![1 m^{3} = 35.287 ft^{3}](https://tex.z-dn.net/?f=1%20m%5E%7B3%7D%20%3D%2035.287%20ft%5E%7B3%7D)
For
:
![6.9\times 35.287 ft^{3} = 243.4803 ft^{3}](https://tex.z-dn.net/?f=6.9%5Ctimes%2035.287%20ft%5E%7B3%7D%20%3D%20243.4803%20ft%5E%7B3%7D)
The significant rule for multiplication, states that the number of significant figures in the answer obtained by multiplication is determined by the value with the lowest number of significant digits.
Since, the minimum number of decimal places in the above multiplication operation is 1 so, the final result must be upto 1 decimal place only.
![243.4803 ft^{3} \simeq 243.5 ft^{3}](https://tex.z-dn.net/?f=243.4803%20ft%5E%7B3%7D%20%5Csimeq%20243.5%20ft%5E%7B3%7D)
Hence, volume in
is 243.5.

Answer:
Dolphins use a method called echolocation to detect things such as obstacles and prey in the water. If a dolphin swimming in seawater at 25°C sends a 220-dB click with a frequency of 120.0 Hz, and then detects the reflection of the click exactly one-twentieth of a second later, approximately how far away is the object?
Answer:
9.72 grams.
Explanation:
From the equation, 4 moles of NH₃ produce 6 moles of water.
Therefore the reaction to product ratio of NH₃ to H₂O is 4:6
and 2:3 into its simplest form.
The number of moles of NH₃ in 6.12 g is:
Number of moles=mass/ RMM
=6.12 g/17 G/mol
=0.36 moles.
Therefore the number of moles of H₂O produced is calculated as follows.
(0.36 Moles×3)2 = 0.54 moles
Mass= Number of moles × RMM
=0.54 moles×18g/mol
=9.72 grams.
