# What is the molality of water?

Sorry, but there actually is an answer. Just like there's a real molar concentration for water by itself (

**55.348 M**), there is a real molality for water by itself (**55.510 m**). Let's say you had 1 L of water. At 25∘C , the density of water is**0.9970749**g/mL , so that's**0.9970749**kg .A.

### What is the molarity of h2o in water?

Grams have a relationship with moles, via the molar mass of a molecule. We know , water molecules 18 g/mole. {16 (O)+1 (H) +1 (H) = 18.} We then take 1,000g / 18g/mole = 55.5555 moles. So, H2O has a molarity of

**55.5**.#### What are the units of molarity?

**Molarity**(M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to**measure**the concentration of a solution.**Molarity**can be used to calculate the volume of solvent or the amount of solute.#### What is a mole of oxygen?

There is a unique relationship between**molar mass**and atomic weight: Oxygen's atomic weight is 16.00 amu.**1 mole**of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the**molar mass**(g/mole) of oxygen?**Molar mass**(in grams) is always equal to the atomic weight of the atom!#### What is the number Mol?

Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to**6.022**×**10**mol^{23}^{-}^{1}and is expressed as the symbol N_{A}.

B.

### How much is a mole of water?

weight of water =

One mole of water weighs

Unless you have a good sense of mass, this value probably doesn't have much meaning to you. It's easier to grasp how much water is in a mole if you find the volume of this amount of mass.

**18.0152**g.One mole of water weighs

**18.0152**grams.Unless you have a good sense of mass, this value probably doesn't have much meaning to you. It's easier to grasp how much water is in a mole if you find the volume of this amount of mass.

#### What is the volume of a mole of water?

**Water**at STP(Standard Temperature 25°C and**1**atm Pressure) is actually in Liquid State, the statement you mentioned is only applicable to Gases. Therefore,**Volume of 1 mole of Water**= 18 ml.#### How many molecules of water are there in one mole of h20?

If you have a compound like H_{2}O, then: one mole of water contains**6.02**x**10**of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 10^{23}MOLECULES^{24}atoms in a mole of water.#### Where did Avogadro live?

Lorenzo Romano Amedeo Carlo Avogadro de**Quaregna**e di Cerreto - better known as Amedeo Avogadro - was born in Turin, the capital city of Piedmont (now part of northern Italy) on June 9th, 1776.
