Answer: -
3.151 M
Explanation: -
Let the volume of the solution be 1000 mL.
At 25.0 °C, Density = 1.260 g/ mL
Mass of the solution = Density x volume
= 1.260 g / mL x 1000 mL
= 1260 g
At 25.0 °C, the molarity = 3.179 M
Number of moles present per 1000 mL = 3.179 mol
Strength of the solution in g / mol
= 1260 g / 3.179 mol = 396.35 g / mol (at 25.0 °C)
Now at 50.0 °C
The density is 1.249 g/ mL
Mass of the solution = density x volume = 1.249 g / mL x 1000 mL
= 1249 g.
Number of moles present in 1249 g = Mass of the solution / Strength in g /mol
= 
= 3.151 moles.
So 3.151 moles is present in 1000 mL at 50.0 °C
Molarity at 50.0 °C = 3.151 M
The surface waves are the type of seismic waves that produce
the most severe ground movement. This wave is slow in nature and so produces a rolling
effect similar to a surface wave in a pond. This kind of wave is far more
devastating than the P waves and the S waves. The surface waves have the
capacity to shake a building from side to side until it collapses. This kind of
wave moves in a pattern similar to a circle. It actually originates at a point
and then start moving outwards in a circle.
The brain is part of the central nervous system.
Nerves and sensors are part of the peripheral nervous system. Only the brain and spinal cord make the central nervous system.
