∙ 12y agoOne drop of water has the volume of about 0.05 mL.
Because the density of water is 1, the mass is 0.05 g. The molar mass of water (H2O) is 18.0 grams/mol (1.008 + 1.008 + 16.0). This means there is one mole of water in 18.0 grams. One mole is 6.02 × 1023 molecules.
Then you can convert grams to number of atoms:
0.05 grams ÷ 18.0 grams × (6.02 × 1023 molecules) = 1.67× 1021 molecules

∙ 17y ago(oh, boy, try to stay focoused on this one :)) Okay, one mole of molecules of water, or about 60,200,000,000,000,000,000,000,000 molecules of water, weighs about (16 + 1 + 1) 18 grams. There are also about 8 electrons per molecule (I believe, please correct me if I am incorrect), and a drop of water is about a mililiter. 18 grams of water therefore has 4,820,000,000,000,000,000,000,000 electrons (8 X 6.02X10^23). 1 mililiter is 1/1000 L, so the water would have about 4.82 X 10^21, (4.82e+24/1000), or 4,820,000,000,000,000,000,000 electrons.

∙ 12y agoThe reactants of water H (2) + O (2) exist as diatomic molecules only. Therefore, 1 mol of Hydrogen + 1 mol of Oxygen will give 2H(2)O (or 2 mols of Water).
Water always exists as a diatomic molecule as well, and this is why it will always have 2 molecules as the most basic possible ratio.

∙ 11y agoestimating ---- there are about 20 drops per ml.
not estimating --- 1 mole of water is 18g and thus 18 ml
1 mole contains 6.022 x 10^23 molecules.
1 drop x (1 ml / 20 drops) x (1 mole / 18 ml) x (6.022x10^23 molecules / 1 mole)
rounding to estimate = (6x10^23) / (20X18) = 1.67 x 10^21 molecules
check my math with a calculator... I'm just estimating

The bonds that link many water molecules together to form a water drop are bonds.?
Hydrogen.
A drop of water has a volume of 0.05mL how many water molecules does it contain?
How big is a drop? "A drop" is not a precise measurement. It depends on a number of factors. If you measure how big the drops of water are you're talking about, (in millilitre) then you could figure out the number of molecules based on the fact that Avogadro's number of water molecules have a volume of about 18 milliliters. Avogadro's number is 6.022 * 1023 (particles) per mole One drop: average volume about 0.05 ml = 0.05 g Molar mass of water 18.01 g/mol Meaning: about 1.7*1021 molecules in a drop of water: don't start counting them!!
Why a drop of water put on a glass plate spreads?
because the cohesion of water molecules is less stronger than the adhesion of the water molecules
How many molecules of water H20 contain2.60x1023molecules of water?
Of course, 6,022.10e23 molecules.
How many molecules of water does a 50g sample of H2O have?
The number of water molecules is 16,728.10e23.
The bonds that link many water molecules together to form a water drop are bonds.?
Hydrogen.
Why does drop of water appear like pearl?
A drop of water appears like a pearl due to the cohesive forces among its molecules. Forces of attraction between water molecules and other molecules called adhesive forces.

Does water have one or many cells?
A water molecule has 3 atoms. Water (like a drop, or cup) is made of many molecules and is in cells. It is not however made up of cells.
Why a drop of water put on a glass plate spreads?
because the cohesion of water molecules is less stronger than the adhesion of the water molecules
Why does the freezing point of water drop when salt is added?
As explanation may be the interactions between the molecules of water and the molecules of the solute; the entropy of the solute is then decreased.
How many many water molecules are in a drop of water?
The reactants of water H (2) + O (2) exist as diatomic molecules only. Therefore, 1 mol of Hydrogen + 1 mol of Oxygen will give 2H(2)O (or 2 mols of Water). Water always exists as a diatomic molecule as well, and this is why it will always have 2 molecules as the most basic possible ratio.
Does the pressure of a liquid depend on its density?
Density is an intrinsic property, and as such it does not depend on the size of the object. A drop of water will have a density of 1g/ml whether it is a big drop, or a very small drop.
Why is the ink drop spread into the beaker of water?
The molecules in the drop of ink will diffuse through the entire beaker of water. This will result in a homogeneous solution because of diffusion. This will only happen if the ink is of similar density to water.
How many molecules of water are present in 1g of water?
The answer is 0,166.10e23 molecules.
How many molecules of water H20 contain2.60x1023molecules of water?
Of course, 6,022.10e23 molecules.
How many molecules of water does a 50g sample of H2O have?
The number of water molecules is 16,728.10e23.
