How many molecules of H2O are in 54.3 g H2O?
To find the number of molecules in 54.3 g of water (H2O), you first need to convert the mass of water to moles using the molar mass of water (18.015 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. The calculation would be: 54.3 g / 18.015 g/mol = 3.013 moles, then, 3.013 moles * 6.022 x 10^23 molecules/mol = 1.816 x 10^24 molecules of H2O in 54.3 g of water.

To find the number of molecules in 36.0 g of H2O, you first need to convert the grams to moles using the molar mass of water (18.015 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules.
How many molecules are in 6.9 g H2O?
To determine the number of molecules in 6.9 g of water (H2O), you first need to convert grams to moles. The molar mass of water is approximately 18 g/mol. Therefore, 6.9 g is equal to 6.9/18 = 0.383 moles of water. Next, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in 0.383 moles of water, which is approximately 2.3 x 10^23 molecules.
How many molecules are in 2.81g H2O?
To calculate the number of molecules in 2.81g of H2O, you first need to convert grams to moles using the molar mass of water (18.015 g/mol).

How many molecules are there in 200 grams of h2o?
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
How many hydrogen atom present in 1 picolitre of water?
To find no; of atoms of hydrogen, we need to find the no; of water molecules in 1 pL of water. Density of water = mass/volume = 1 g/cc mass of 1pL of water = density * volume = 1 g/cc * 10-9 cc (1L = 103 cc, so 10-12 L = 10-9 cc) = 10-9 g 18g of H2O = 6.023 * 1023 molecules. hence, 10-9 g of H2O = 3.346 * 1013 molecules of H2O 1 molecule of H2O = 2 atoms of H hence 1pL = 6.692* 1013 atoms of H
How many molecules are there in 95.2 g of water?
To find the number of molecules in 95.2 g of water, first calculate the number of moles using the molar mass of water (18.015 g/mol). Next, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. So, (95.2 , \text{g} \times \frac{1 , \text{mol}}{18.015 , \text{g}} \times 6.022 \times 10^{23} , \text{molecules/mol}) gives you the number of molecules.
What is the number of molecules in 16.75 grams of H2O?
To calculate the number of molecules in 16.75 grams of H2O, we first need to convert grams to moles (using the molar mass of H2O), and then convert moles to molecules using Avogadro's number.
