Plugging in the mass of 1 mole of water and its density gives you: Volume = 18 grams / 1 gram/mL. Volume = 18 mL.
How do you calculate volume from moles of water?
There are two steps:
- Multiply the volume by the density to get the mass.
- Divide the mass by the molar mass to get the number of moles.
What is 1 mole in terms of volume?
Moles in terms of volume
One mole of all gaseous substances at 273 K and 1 atm pressure occupies a volume equal to 22.4 liter or 22,400 ml.
How many liters are in 1 mole of H2O?
One mole of water has a mass of 18 grams and volume of 18 milliliters or 0.018 liters.
How many grams of water are in 1 mole of water?
The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formula mass are numerically the same.
What is the value of 1 mole?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Is mole a volume?
1 mol of any gas at STP has a volume of 22.4 L.
What is the volume of 1 mole of gas at STP?
What is the volume of 1 mole of an ideal gas at STP (Standard Temperature and Pressure = 0 °C, 1 atm)? So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.
What is the volume of 1 mole of H2O at STP?
Since at STP water occupies very nearly 1 cc per gram, and since 1 mole of water molecules weighs very nearly 18 grams, the molar volume of water is about 18 cc.
What is the volume of a water molecule?
The volume of one water molecule is 2.99×10-23cm3 .
How many molecules of water are there in 1 gram of water H2O?
or 1 g of water contains (6.022 x 1023)/ 18 water molecules and the number comes out to be 3.3455 x 1022. So the number of water molecules present in 1 g of water is 3.3455 x 1022.
How many molecules are in 2 moles of water?
The number 6.022 x 1023 is known as Avogadro’s Number. A mole of carbon-12 atoms has 6.022 x 1023 carbon-12 atoms. A mole of apples has 6.022 x 1023 apples. A mole of water has 6.022 x 1023 water molecules.
