answer yes if the substance becomes part of the filtrate or answer no if the molecule does not become part of the filtrate
SVETLANKA909090 [29]

Yes, the substance becomes the part of filtrate. No, the molecule does not become part of the filtrate.

<h2>What is filtrate?</h2>

The most common example is making tea. While preparing tea, a filter or a sieve is used to separate tea leaves from the water. Through the sieve pores, only water will pass. The liquid which has obtained after filtration is called the filtrate; in this case, water is the filtrate.

<h3>Which substance becomes the part of the filtrate?</h3>

The substances that are normally found in the filtrate  are plasma components (such as water, nutrients, dissolved gases, electrolytes, and metabolic wastes) excluding plasma proteins and blood cells.

<h3>Why molecule becomes the part of the filtrate?</h3>

Proteins are large molecules that cannot pass the wall of capillaries during  filtration, hence, this molecule is not normally part of the  filtrate.

The forensic technician at a crime scene has just prepared a luminol stock solution by adding 17.0 \({\rm g}\) of luminol into a
maria [59]

Answer:

1.28 M

Explanation:

Step 1: Given data

Mass of luminol (solute): 17.0 g

Volume of water: 75.0 mL (this is also the volume of solution)

Step 2: Calculate the moles corresponding to 17.0 g of luminol

The molar mass of luminol is 177.16 g/mol.

17.0 g × 1 mol/177.16 g = 0.0960 mol

Step 3: Calculate the molarity of the solution

We will use the definition of molarity

M = moles of solute / liters of solution

M = 0.0960 mol / 0.0750 L = 1.28 M
