P waves are faster S wave are slower P waves can pass through both solids and liquids S waves bounce of solids
Answer:
Explanation:
Hello,
In case, for the boiling point raise we can write:
Whereas T2 accounts for the boiling point of the solution which is 101.286 °C, T1 the volume of pure water which is 100.000 °C, i the van't Hoff factor that for this problem is 1 due to the solute's non-volatility, m the molality of the solute and Kb the boiling point constant that is 0.512 °C/m. In such a way, the change in the temperature is:
The molality is computed from the boiling point raise:
The moles are computed by multiplying the molality by the kilograms of water as the solvent (0.02002g):
And the molecular mass by dividing the mass of the solute by its moles:
Best regards.
Answer:
0.71
Explanation:
The molecular mass of NaCl is, 23+35.5
= 58.5
1 mole means molecular mass (in gram)
In 58.5 gm NaCl there is 1 mole.
So, 42.1 gm NaCl contains 42.1/58.5 =0.71 moles.
This is because fall has more weather patterns which are repetitive than summer.
<h3>What is Weather?</h3>
This is defined as the atmospheric condition of a particular place at a given period of time.
The repetitive weather patterns have various effects on the stars which is why they were studied.
