How many mongo seed are equal to 3.50 moles of mongo seeds?​
frozen [14]

Answer:

The correct answer is - 2.107 x 10^24 mango seeds.

Explanation:

Given:-

number of moles of mango seeds = 3.50 mol

Solution:-

1 mol of mango seeds = 6.02 x 10^23 mango seeds

6.02 x 10^23 is Avagadro numbers

1 mole is the number of particles contained in a substance . The number of moles can also be calculated by dividing the mass by the molar mass of the element or molecule of the substance  with the Avogadro's number.

Therefore,

3.50 mol of mango seeds = 3.50 x 6.02 x 10^23 mango seeds

3.50 mol of mango seeds = 21.07 x 10^23 mango seeds

3.50 mol of mango seeds = 2.107 x 10^24 mango seeds

What structures are present in plant and animal cells but not in a bacterial cell?
otez555 [7]

Answer:

Structures that are present in plant cells and animal cells are membrane-bound organelles. For example, nucleus, mitochondria, and/or chloroplasts are not present in bacteria.

Explanation:

This is because bacteria are prokaryotic cells while plants and animals are eukaryotic cells.

Prokaryotic cells lack membrane-bound organelles like eukaryotic cells. Prokaryotic cells do not have a nucleus or organelles like mitochondria and chloroplasts.
