What is the chemical formula for 12 molecules of water?
The chemical formula for water is H2O. When you have 12 molecules of water, the chemical formula would be 12H2O.
How many molecules are there in the formula 6CuCl?
The formula 6CuCl represents 6 molecules of copper(II) chloride, CuCl2. Therefore, there are 6 x Avogadro's number (6.022 x 10^23) molecules in 6CuCl, which is 3.6132 x 10^24 molecules.
What has 10 water molecule?
A substance that contains 10 water molecules is often referred to as a "decahydrate." In chemistry, this term is used to describe a hydrate in which ten water molecules are associated with each formula unit of the compound. An example of a decahydrate is copper(II) sulfate decahydrate (CuSO₄·10H₂O), commonly known as blue vitriol.
What would you needto do to calculate the molality to 10 molecules of NaCl in 200 molecules of water?
Molality of a solution is defined as the number of gram moles, for molecular compounds, or gram formula unit masses, for ionic compounds, mixed with each kilogram of solvent. Sodium chloride is the solute in the question, and water is the solvent. Avogadro's Number is defined as the number of formula units required to constitute one gram formula unit and has the value of about 6.022 X 1023. Therefore, 10 formula units of NaCl constitutes 10/(6.022 X 1023) or about 1.6606 X 10-23 gram formula unit. The gram molecular mass of water is 18.0518. Therefore, 200 molecules of water contains (200)(18.0518)/(6.022 X 1023) or about 599.5 X 10-23 grams or 0.5995 X 10-23) kilograms. Therefore, the molality of the given mixture is 1.6606/0.59995* or about 2.768. ________ *The number 10-23 appears in both numerator and denominator, and therefore need not be included in this fraction.
How many water molecules would be released in a reaction when 10 glucose molecules are linked together?
Amylase is a catalyst (enzime).Amylose is the polysaccharide.
What is the chemical formula for 12 molecules of water?
The chemical formula for water is H2O. When you have 12 molecules of water, the chemical formula would be 12H2O.
Sodium chromate how many water molecules per formula?
Sodium chromate usually does not contain any water molecules per formula. The formula for sodium chromate is Na2CrO4, which does not have any water molecules associated with it.
What is the number of water molecules bound per formula unit of KAlSO42?
KAl(SO4)2 is the formula unit found in alum. The formula of alum is KAl(SO4)2 .12H2O There are twelve water molecules present per formula unit, it is a sometimes called dodecahydrate.
The hydrate sodium sulfate on heating the hydrate how many moles of water should be driven off per mole of hydrate?
For sodium sulfate decahydrate (Na2SO4·10H2O), on heating, 10 moles of water molecules will be driven off per mole of the hydrate. Each formula unit of the hydrate contains 10 water molecules.
How many hydrogen atoms are needed to form five water molecules?
Chemical formula for water is H2O. One water molecule has 2 hydrogen atoms. That means 10 hydrogen atoms are needed to form five water molecules.The ration between hydrogen and oxygen in a water molecule is 2:1. In five water molecules, there are five oxygen atoms. According the ratio, there are 10 hydrogen atoms.
How many water molecules are in a block of ice containing 1.00 mol of water (H2O)?
How many formula units make up 2.00 g of magnesium chloride
How many molecules are there in the formula 6CuCl?
The formula 6CuCl represents 6 molecules of copper(II) chloride, CuCl2. Therefore, there are 6 x Avogadro's number (6.022 x 10^23) molecules in 6CuCl, which is 3.6132 x 10^24 molecules.
How many molecules are in the formula 3H2O?
There are 6 molecules in the formula 3H2O: 3 molecules of water (H2O) each composed of 3 atoms (2 hydrogen and 1 oxygen).
How many water molecules are tied up per formula unit of a compound that is an octahydrate?
An octahydrate contains 8 water molecules per formula unit.
What has 10 water molecule?
A substance that contains 10 water molecules is often referred to as a "decahydrate."

What is dihydrate formula?
A dihydrate formula indicates that a compound contains two molecules of water. It is represented by the prefix "di" followed by the chemical formula of the compound and then "hydrate." For example, calcium sulfate dihydrate has the formula CaSO4·2H2O, indicating that it contains two molecules of water.
