A solution is made by dissolving 0.565 g of potassium nitrate in enough water to make up 250. mL of solution. What is the molari
aalyn [17]
<h3>Molar mass of Potassium Nitrate:-</h3>

\\ \large\sf\longmapsto KNO_3

\\ \large\sf\longmapsto 39u+14u+3(16u)

\\ \large\sf\longmapsto 53u+48u

\\ \large\sf\longmapsto 101u

\\ \large\sf\longmapsto 101g/mol

Now

\boxed{\sf No\:of\:moles=\dfrac{Given\:mass}{Molar\:mass}}

\\ \large\sf\longmapsto No\:of\:moles=\dfrac{0.565}{101}

\\ \large\sf\longmapsto No\:of\:moles=0.005mol

We know

\boxed{\sf Molarity=\dfrac{Moles\:of\:solute}{Vol\:of\:Solution\:in\:L}}

\\ \large\sf\longmapsto Molarity=\dfrac{0.005}{\dfrac{250}{1000}L}

\\ \large\sf\longmapsto Molarity=\dfrac{0.005}{0.250}

\\ \large\sf\longmapsto Molarity=0.02M

You've collected several samples of DNA at a crime scene, but they are all short strands. What technique would you rely on to as
Nezavi [6.7K]

Option C

PCR technique would you rely on to assist with analysis

<u>Explanation:</u>

Experts elaborate this tiny specimen by a means acknowledged as a polymerase chain reaction, or PCR. PCR produces replicas of the DNA significant like DNA duplicates itself in a cell, offering virtually any coveted measure of the ancestral element.

Following the accumulation of biological matter from a crime picture, the DNA is beginning derived from its biological source element and then estimated to assess the number of DNA rescued. Subsequent detaching the DNA from its cells, precise areas are imitated with a procedure acknowledged as the polymerase chain reaction, or PCR.
