so 20 g of water = 1.11 mol of water.
How much is a mole?
One mole of a substance is equal to 6.022 × 1023 units of that substance (such as atoms, molecules, or ions). The number 6.022 × 1023 is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.
Is moles the same as grams?
| Known Information Multiply By Result | Moles of substance (mol) Avogadro's constant (atoms/mol) Atoms (or molecules) | Mass of substance (g) 1/Molar mass (mol/g) × Avogadro's constant (atoms/mol)) Atoms (or molecules) |

How many steps is it to convert from grams to moles?
There are three steps to converting grams of a substance to moles.
What is a 1 mole?
A mole is defined as 6.02214076 × 10 23 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.
How many grams is 5 moles oxygen?
Therefore, 160 g of oxygen is present in 5 moles.
How do you find moles in grams of a compound?
Divide the mass of the compound in grams by the molar mass you just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or 1.39 moles.

How many moles are in 96g of oxygen?
Therefore, according to the question, it is given that, weight of ${O_2}$ is 96 grams and is contained in the volume of vessel 2 liters. Hence, the number of moles is 3 .
How many grams are in oxygen?
Explanation: Oxygen has a molar mass of 16.00 g/mol . One mole of CO2 contains 32.00 grams of oxygen. One mole equals 22.4L at standard temperature and pressure.
How many liters are in 1 mole of O2?
The molar volume of an ideal gas is ~ 22.4 liters per mole (we'll consider O2 to be an ideal gas for these purposes, and 22.4 is an approximation that varies with temperature, it's 22.414 at 0C).
What is the volume of 16 grams of O2 at STP?
1 mole of a gas occupy =22.4L volume at STP therefore, 16gO2 gas =0.5 mole of O2 gas will occupy =0.5×22.41= 11.2L at STP.
