Answer 2

Calculating the Number of Molecules in 36 kg of Water (H2O)

To calculate the number of molecules in 36 kg of water (H2O), we can use the following steps:

1. Calculate the number of moles of water in 36 kg. 2. Use Avogadro's number to convert the moles of water to the number of molecules.

Step 1: Calculate the Number of Moles of Water in 36 kg

The molar mass of water (H2O) is approximately 18.01528 g/mol.

To convert 36 kg to grams: - 1 kg = 1000 grams - Therefore, 36 kg = 36,000 grams

Now, we can calculate the number of moles of water: - Number of moles = Mass (in grams) / Molar mass - Number of moles = 36,000 g / 18.01528 g/mol - Number of moles ≈ 1996.45 moles

Step 2: Convert Moles to Number of Molecules Using Avogadro's Number

Avogadro's number is approximately 6.022 x 10^23 molecules/mol.

Now, we can calculate the number of molecules: - Number of molecules = Number of moles * Avogadro's number - Number of molecules ≈ 1996.45 moles * 6.022 x 10^23 molecules/mol - Number of molecules ≈ 1.202 x 10^27 molecules

Therefore, 36 kg of water (H2O) contains approximately 1.202 x 10^27 molecules.
