To calculate the number of molecules in 1L of water at 4°C, we need to use Avogadro's number and the molar mass of water.
Avogadro's number (NA) is approximately 6.022 x 10^23 molecules/mol.
The molar mass of water (H2O) is approximately 18.015 g/mol.
To convert 1L of water to grams, we need to use the density of water, which is approximately 1 g/mL.
1L of water is equivalent to 1000 mL.
Mass of 1L of water = 1000 mL * 1 g/mL = 1000 g.
Now we can calculate the number of moles of water:
Number of moles of water = Mass of water / Molar mass of water
Number of moles of water = 1000 g / 18.015 g/mol ≈ 55.51 mol
Finally, we can calculate the number of molecules:
Number of molecules = Number of moles of water * Avogadro's number
Number of molecules = 55.51 mol * 6.022 x 10^23 molecules/mol ≈ 3.34 x 10^25 molecules
Therefore, there are approximately 3.34 x 10^25 molecules in 1L of water at 4°C.
Avogadro's number (NA) is approximately 6.022 x 10^23 molecules/mol.
The molar mass of water (H2O) is approximately 18.015 g/mol.
To convert 1L of water to grams, we need to use the density of water, which is approximately 1 g/mL.
1L of water is equivalent to 1000 mL.
Mass of 1L of water = 1000 mL * 1 g/mL = 1000 g.
Now we can calculate the number of moles of water:
Number of moles of water = Mass of water / Molar mass of water
Number of moles of water = 1000 g / 18.015 g/mol ≈ 55.51 mol
Finally, we can calculate the number of molecules:
Number of molecules = Number of moles of water * Avogadro's number
Number of molecules = 55.51 mol * 6.022 x 10^23 molecules/mol ≈ 3.34 x 10^25 molecules
Therefore, there are approximately 3.34 x 10^25 molecules in 1L of water at 4°C.
