How many sulfur atoms are there in 25 molecules of C4H4S2?
50
To find the number of sulfur atoms in 25 molecules of C4H4S2, we first need to determine the molar mass of C4H4S2 and the ratio of sulfur atoms to molecules in the compound.
1. Calculate the molar mass:
- The molar mass of carbon (C) is 12.01 g/mol.
- The molar mass of hydrogen (H) is 1.01 g/mol.
- The molar mass of sulfur (S) is 32.07 g/mol.
- C4H4S2 consists of 4 carbon atoms, 4 hydrogen atoms, and 2 sulfur atoms.
- Molar mass of C4H4S2 = (4 * molar mass of C) + (4 * molar mass of H) + (2 * molar mass of S).
2. Find the ratio of sulfur atoms to molecules in C4H4S2:
- C4H4S2 contains 2 sulfur atoms in each molecule.
3. Calculate the number of sulfur atoms in 25 molecules of C4H4S2:
- Number of sulfur atoms = 2 sulfur atoms/molecule * 25 molecules.
Let's calculate the answer step by step:
1. Molar mass of C4H4S2:
- Molar mass of C4H4S2 = (4 * 12.01 g/mol) + (4 * 1.01 g/mol) + (2 * 32.07 g/mol).
Calculate the molar mass:
Molar mass of C4H4S2 = (48.04 g/mol) + (4.04 g/mol) + (64.14 g/mol).
Molar mass of C4H4S2 = 116.22 g/mol.
2. Ratio of Sulfur atoms to molecules:
- In C4H4S2, there are 2 sulfur atoms in each molecule.
3. Number of sulfur atoms in 25 molecules of C4H4S2:
- Number of sulfur atoms = 2 sulfur atoms/molecule * 25 molecules.
Calculate the number of sulfur atoms:
Number of sulfur atoms = 2 * 25.
Number of sulfur atoms = 50.
Therefore, there are 50 sulfur atoms in 25 molecules of C4H4S2.
There are 2 atoms of sulfur in a molecule of C4H4S2.
