. Blood should NOT be stored in which way? As a scraping Dried on a swab In an airtight container Dried on the object
notsponge [240]

Blood should NOT be stored in an airtight container

<h3>Explanation:</h3>

We can store blood by dried it on a swab. To collect the dried blood, we should moisten a sterile cotton swab using distilled water or tap water, then shake the swab to remove excess water. Gently swab the stain with the moistened swab tip until the swab thoroughly absorbs the blood.

We can store blood also in the dried blood stains and as a scraping. The fresh collected blood, dried blood stains, wet blood stains are contained the DNA.

Airtight containers are the plastic used to make the durable containers and it is free from BPA and has been graded to be safe to be used with food supplies. ​The lid of this container has an innovative airtight mechanism which helps to maintain the airtight environment inside the container.

According to book "Criminal Investigation" By Ronald F. Becker on page 114, the airtight containers can cause condensation of moisture within the container and result in bacteria that can destroy, alter or contaminate the blood.

Blood components should be stored at temperatures storage in accordance with the requirements listed. Failure to follow correct storage requirements result in decreased transfusion efficacy

A 5.21 mass % aqueous solution of urea (CO(NH2)2) has a density of 1.15 g/mL. Calculate the molarity of the solution. Give your
Alex777 [14]

Answer:

Molarity is 0.99 M

Explanation:

5.21% by mass, is a sort of concentration which shows the mass of solute in 100 g of solution.

Molarity is a sort of concentration that indicates the moles of solute in 1 L of solution (mol/L)

Let's find out the volume of solution by density.

Solution density = Solution mass / Solution volume

1.15 g/mL = 100 g / Solution volume

Solution volume = 100 g / 1.15 g/mL → 86.9 mL

We must have the volume of solution in L, so let's convert it.

86.9 mL / 1000 = 0.0869 L

Now, we have to determine the moles of solute (urea)

5.21 g . 1 mol / 60 g = 0.0868 moles

Mol/L = Molarity → 0.0868 moles / 0.0869L  = 0.99 M
