Answer:
I learned that Spinach and broccoli are high in Iron.
Explanation:
I thought it was cool because before I thought iron was only available in the grains food group.
The mass of 3.41×10²⁴molecules of propylamine is 33.45 gms.
<h3>What is avogador's no. ?</h3>
Avogadro's number, the number of units in one mole of any substance (defined as its molecular weight in grams), is equal to 6.02214076 × 10²³.
<h3>How to determine the molar mass of compound ? </h3>
To this problem we first need to calculate the molar mass of the given compound. as follows:
3×12+1×9+1×14 = 59
In the next step, we simply apply the formula to calculate the mass of the compound. it is
No. of molecules ÷ Avogadro's no. × molar mass of the compound
3.41 x 10²⁴÷6.02×10²³×54= 33.43gms
Hence, the mass of 3.41×10²⁴molecules of propylamine is 33.45 gms.

Answer:
No , there is no relation between DNA fingerprinting and actual fingerprints.
Explanation:
In DNA fingerprinting, a solution converted into the form of gel is used to
differentiate DNA molecules that move with different speed. A DNA molecule of large size moves slowly while a DNA molecule of smaller size moves rapidly.
In gel electrophoresis, DNA molecules are separated based on size. Bands of DNA are formed when DNA molecule fall into discrete sizes. These bands occur in the form of small rectangular bands with each band signifying a specific size.
