Your question: How many molecules are there in 0 5 moles of water?

How many molecules are there in 0.5 moles of water?

Answer: A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water. 0.5 x 6.022 x 10^23 molecules of water.

What is 0.5 mole water?

For 1 mole of water =molecular mass of water (H2O)in grams =mass of 2H atoms +mass of O atoms =2×1+16. =2+16. =18 grams ⇒ for 1 mole. For 0.5 moles = 18×0.5. = 9.0 grams.

How do you find the mass of 0.5 moles of water molecules?

Calculate the mass of. 0.5 mole of water molecules

  1. you are intelligent man. write answer.
  2. Mass of 1 mole of H2O molecule = (1 x 2 + 16) = 18 u. Mass of 0.5 mole of H2O molecule = (18 x 0.5) u =9 u.

What is the mass of 5 mole of water molecules?

Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

How many molecules are there in 0.5 mol of co2?

since 1 mol represents 6.02 x 10^23 particles, there are 0.5×6. 02×10^23 particles (molecules) of carbon dioxide.

What is the number of molecules in 0.25 mole of oxygen?

0.25 moles of oxygen there is 6.023/4×10^23 molecules.

What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.

What is the mass of 0.5 mole of ammonia and water?

Hence the mass of 0.5 moles of NH3 = 17/2 u (OR) 8.5 u.

What is the mass of 0.5 mole of S?

Step-by-step explanation:

One mole of sulphur contains 32 amu. so 0.5 mole will have 16 amu.

How many number of molecules are there in 22g of co2?

6.02*10^23 molecules equals 1 mole.

How many moles are in 90 grams of water?

A mole of a compound is a number of grams equal to the atomic weight of a molecule of the compound, so for water we have 2 hydrogen atoms and one oxygen, so the atomic weight of water is 1+1+16=18, so a mole of water is 18 grams. We have 90g of water so we have 90/18 = 5 moles of water.

What is the mass of 10 mole H2O?

So, 10 mole of water will weigh (18×10) = 180g.

How many moles are present in 2.3 gram of any?

Solution: Molecular mass of Sodium is 23 u. So, 23 g of sodium is equal to 1 mole. The number of mole in 2.3 g = 2.3 / 23 = 0.1 mole.
