The answer is 5.5x10 to the power of 27.
6.02x10 to the power of 23 is how many particles are in one mole.
Therefore, if there are 922 moles then by cross-multiplying I multiplied 6.02x10 to the power of 23 with 922 and that's how I got the answer of 5.5x10 to the power of 27.

Answer:
LiCl = 0.492 m
Explanation:
Molal concentration is the one that indicates the moles of solute that are contained in 1kg of solvent.
Our solute is lithium chloride, LiCl.
Our solvent is distilled water.
We do not have the mass of water, but we know the volume, so we should apply density to determine mass.
Density = mass / volume
Density . volume = mass
1 g/mL . 19.7 mL = 19.7 g
We convert g to kg → 19.7 g . 1 kg / 1000g = 0.0197 kg
Let's determine the moles of LiCl
0.411 g . 1 mol / 42.394 g = 9.69×10⁻³ moles
Molal concentration (m) = 9.69×10⁻³ mol / 0.0197 kg → 0.492 m
Answer:
The P Wave travels through Earth's crust more quickly than the S wave travels
Explanation:
P and S waves are types of seismic waves that travel through Earth's crust.
Some basic data we can read from this graph are:
- it takes around 13 minutes for P wave to travel 10000 kilometers.
- it takes around 25 minutes for S wave to travel 10000 kilometers.
Based on this data, we can conclude that, since P wave takes less time then S wave to travel the same distance, that means that it moves through Earth's interior more quickly.
Decrease the temperature and increase the presure
