How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
How many molecules of H2(g) are there in a 21.25 gram sample?
To calculate the number of molecules, you first need to determine the number of moles of H2 in the 21.25 gram sample using the molar mass of H2 (2 grams/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many molecules are in 1 gram of carbon dioxcide?
There are approximately 1.13 x 10^22 molecules in 1 gram of carbon dioxide.
How many molecules are in sample 57.45 CF2Cl2?
To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.
How many atoms are in a 12.0 grams sample of sodium?
There are approximately 6 x 10^22 atoms in a 12.0 gram sample of sodium.
