1)
Volume = 19 / 1000 = 0.019 L
n = M * V
n = 0.100 * 0.019
n = 0.0019 moles
__________________________
2)
M₁ * V₁ = M₂* V₂
5.0 * V₁ = 1.0 * 152
5.0 V₁ = 152
V₁ = 152 / 5.0
V₁ = 30.4 mL

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
Hello there!
Sedimentary rocks are formed due to layers so the answer is A.

the answer would be winter because the north would be facing away from the son therefor making the northern states cold.
Answer:
Density is an intensive property
Explanation:
The intensive properties don´t depend on mass or size, if you have a liter of water, this litter have a density equal 1000 kg/m^3. If zo have 250 liters of water, the density is 1000 kg/m^3 too.
The density does not change with the addition or substraction of matter.
I hope I have been clear.
