Eukaryotic cells have nuclear membranes, whereas prokaryotic cells do not. They both have a nuclear body, but the prokaryotic cell does not have an actual nucleus. Both cells have DNA, they just have it constructed differently. Also, eukaryotic cells are larger than prokaryotic cells, not smaller. Hope this helps!

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.
