There are approximately 1.0545 x 10^24 atoms in 1.75 mole of CHCl3.
To calculate the number of atoms in 1.75 mole of CHCl3, we need to use Avogadro's number, which is 6.02 x 10^23 atoms per mole. The atomic mass of CHCl3 can be calculated by adding up the atomic masses of its constituent atoms. Carbon has an atomic mass of 12.01 g/mol, hydrogen has 1.01 g/mol, chlorine has 35.45 g/mol, and there are 3 chlorine atoms in CHCl3. So, the total atomic mass of CHCl3 is 12.01 + (1.01 x 3) + 35.45 = 119.48 g/mol. Therefore, 1.75 mole of CHCl3 contains (1.75 mol) x (6.02 x 10^23 atoms/mol) = 1.0545 x 10^24 atoms.

To find the number of atoms in 1.75 moles of CHCl3, multiply 1.75 moles by Avogadro's number, then by the number of atoms per CHCl3 molecule to get approximately 5.26925 × 10^24 atoms.
To calculate the number of atoms in 1.75 moles of CHCl3, we'll follow a few simple steps. First, remember that 1 mole of any substance contains Avogadro's number of particles, which is 6.022 × 10^23 particles/mole. The formula CHCl3 consists of 1 atom of carbon, 1 atom of hydrogen, and 3 atoms of chlorine for a total of 5 atoms per molecule.
So, if we have 1.75 moles of CHCl3, we can multiply this by Avogadro's number to find the number of molecules:
1.75 moles × 6.022 × 102^3 molecules/mole = 1.05385 × 10^24 molecules of CHCl3
Then, we multiply the total number of molecules by the number of atoms per molecule:
1.05385 × 10^24 molecules × 5 atoms/molecule =
5.26925 × 10^24 atoms
Therefore, there are approximately 5.26925 × 10^24 atoms in 1.75 moles of CHCl3.

Answer:
The correct answer is meiosis takes place, making the sperm cell haploid.
Explanation:
From secondary spermatocytes, the formation of haploid male gamete, that is, spermatid takes place. Its formation takes place by the procedure of meiosis, and therefore, it comprises half of the genetic substance as found in in the primary spermatocyte.
In the beginning, spermatid is a round, immotile cell that distinguishes and turns motile and unique by the procedure is known as spermiogenesis.

The percent by mass of carbon in acetic acid (HC2H3O2) is calculated using the molar masses of its constituent elements. Upon calculation, it is determined that the percent by mass of carbon in acetic acid is 40.00%.
To calculate the percent by mass of carbon in acetic acid (HC2H3O2), we need to use the molar masses of the elements involved. The formula for acetic acid includes two carbon atoms, four hydrogen atoms, and two oxygen atoms. Using the given molar masses (carbon: 12.01 g/mol, hydrogen: 1.008 g/mol, oxygen: 16.00 g/mol), the molar mass of acetic acid can be calculated as follows:
Adding these together gives the molar mass of acetic acid as 60.052 g/mol.
To find the percent by mass of carbon, we take the total mass of carbon in the compound and divide it by the total molar mass of the compound:
(24.02 g/mol / 60.052 g/mol) × 100% = 40.00%
Therefore, the percent by mass of carbon in acetic acid is 40.00%.
