Answer:
The answer to your question is below
Explanation:
Data
Substance = NaCl
moles of NaCl = 49
volume = 150 ml
Process
Molarity is a unit of concentration that makes a relation of the moles of a substance and the volume.
Molarity = moles / volume (L)
1.- Convert 150 ml to L
1000 ml ------------------ 1 L
150 ml ----------------- x
x = (150 x 1) / 1000
x = 0.15 L
2.- Substitution
Molarity = 49 / 0.15
Molarity = 326. 7
I have a doubt if the number of moles is 49 moles or 49μmoles
The first step is to use the formula from Boyle's Law.
[(351 L)(1.0 atm)]/(181L) = 1.94 atm.
To determine the depth of the location where the diver was working, 1.94 is multiplied by 10. Therefore, the location of the underwater archaeological site is 19.4 meters below the surface.
I believe the answer is orbital hybridization theory
