Hello, Lindaparker, a spit could form from a rocky headland where prevailing winds would
blow at an angle to the rocky headland, gradually depositing sand and
shingle at that place. A spit is a permanent land form resulting
from marine deposition and wind deposition. It is usually a long and
narrow accumulation of sand or shingle with one joined to the land and
the other end projecting at a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
Answer:
Lavender
Explanation:
Lavender is the anticoagulant, commonly used for hermatology tests
300 milliliter a of
NaOH solution would contain
of NaOH
<u>Solution:</u>
Given volume percentage =
Weight of solute = ![75 g](https://tex.z-dn.net/?f=75%20g)
Consider, ![\bold{\text {volume percentage}=\frac{\text {weight of solute in } g}{\text {volume of solution}} \times 100}](https://tex.z-dn.net/?f=%5Cbold%7B%5Ctext%20%7Bvolume%20percentage%7D%3D%5Cfrac%7B%5Ctext%20%7Bweight%20of%20solute%20in%20%7D%20g%7D%7B%5Ctext%20%7Bvolume%20of%20solution%7D%7D%20%5Ctimes%20100%7D)
![\Rightarrow \text {Volume of solution is }=\left(\frac{75}{25}\right) \times 100](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctext%20%7BVolume%20of%20solution%20is%20%7D%3D%5Cleft%28%5Cfrac%7B75%7D%7B25%7D%5Cright%29%20%5Ctimes%20100)
![\Rightarrow 3 \times 100](https://tex.z-dn.net/?f=%5CRightarrow%203%20%5Ctimes%20100)
Therefore, the answer is 300 ml.
Answer:
0.374 L
Explanation:
Step 1: Given data
Mass of silver nitrate (solute): 15.89 g
Molarity of the solution: 0.250 M
Step 2: Calculate the moles of silver nitrate
The molar mass of silver nitrate is 169.87 g/mol.
![15.89g \times \frac{1mol}{169.87g} = 0.09354mol](https://tex.z-dn.net/?f=15.89g%20%5Ctimes%20%5Cfrac%7B1mol%7D%7B169.87g%7D%20%3D%200.09354mol)
Step 3: Calculate the volume of the solution
The molarity is equal to the moles of solute divided by the liters of solution.
![M = \frac{moles\ of\ solute }{volume\ of\ solution} \\volume\ of\ solution = \frac{moles\ of\ solute}{M} = \frac{0.09354mol}{0250mol/L} = 0.374 L](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7Bmoles%5C%20of%5C%20solute%20%7D%7Bvolume%5C%20of%5C%20solution%7D%20%5C%5Cvolume%5C%20of%5C%20solution%20%3D%20%5Cfrac%7Bmoles%5C%20of%5C%20solute%7D%7BM%7D%20%3D%20%5Cfrac%7B0.09354mol%7D%7B0250mol%2FL%7D%20%3D%200.374%20L)
Due to the significant figures rules, we keep 3 significant figures.
