Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.

What is mass of ammonia?
The molecular mass of ammonia (NH3) is 18.03 grams/mole
How many grams are in half a mole of NaCl?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
How do you convert mol.dm3 to g.dm3?
You look up the molecular mass of the corresponding substance - that tells you how many grams there are per mole. Then you multiply by that number.
What is the mass in grams of one mole of sulfur dioxide SO2?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.S- 32.1O- 16.0SO- 48.1 grams in one mole
If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
What number is written after the isotope when writing the name?
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
The molecular mass of 2 moles in H2SO4?
2 moles H2SO4 (98.086 grams/1 mole H2SO4)= 196.172 grams of sulfuric acid====================
How do calculate how many mole are in grams?
For these conversions, you need the atomic masses of the elements involved in grams. If it is just one element, then you use the atomic mass, but if its a compound, then use the molecular mass (added atomic masses). Take the number of moles and multiply it by the atomic (molecular) mass to get number of grams.
What is the molar mass of dichlorobenzene?
Dichlorobezene can come in ortho,meta, and para configurations. Each of these has a molar mass of 147.0g/mol.
Determine the mass in grams of 0.0458 mole of sulfur?
Multiplying moles of S by molecular mass of it (Sulfer: 32.06 g/mole) gives mass in grams0.0458 mole * 32.06 g/mole = 1.47 g Sulfur
How is the mass in grams of an element converted to the amount of moles?
The formula is number of moles = mass / molecular mass. So say we have 1 mole of water. We look at the periodic table and molecular mass is 1+1+16 = 18g/mol. 1 mole x 18g/mol is 18 grams.
How many grams of sodium chloride is obtained by the action of chlorine with 4 moles sodium?
A mole of an element or compound is 6.022 x 1023 (Avogadro's constant) molecules of that substance. This number is the number of molecules it takes for an amount of substance to have a mass in grams the same as its molecular mass: carbon has a molecular mass of 12, so 6.022 x 1023 (one mole) carbon atoms have a mass of 12 grams. The molecular mass of sodium is 23 (22.989) so one mole of sodium has a mass of 23 grams. Sodium chloride has a molecular mass of 58.44 so a mole of NaCl is 58.44 grams. One mole of sodium will make one mole of sodium chloride. Na + Cl => NaCl So four moles of sodium will make four moles of sodium chloride. 4Na + 4Cl => 4NaCl Four moles of NaCl has a mass of 4 x 58.44 = 233.76 grams.
