How many grams of water are in 1 mole?

Answer 1

This will depend on the substance you are talking about. One mole is by definition equal to 6.02 x 1023 molecules or atoms of the substance, but the weight of one molecule or atom will vary depending on the substance you are referring to.

To figure out the number of grams in one mole of a substance, you need to calculate the molecular weight of the substance. This is done by adding the atomic weight of each ATOM in the molecule. For instance, in the molecule ethanol (C2H6), you would add the weight of the two carbon molecules (12 x 2) to the weight of the six hydrogen molecules (1 x 6) which gives you a total of 30. Therefore, for ethanol, there are 30 g in one mole of ethanol.

Answer 2

To find what you are looking for, referred to the molar mass of a compound in chemistry, you must sum up all the average atomic masses of the elements and their occurrence.

Example: Sucrose, a.k.a. sugar, C12H22O11

element= (occurrence) x (average Atomic Mass)

Carbon= 12x12.011= 144.13

Hydrogen= 22x1.0079 =22.174

Oxygen= 11x15.999= 175.99

144.13 + 22.174 + 175.99 = 342.29.

Therefore, the mass of one mole of sucrose is 342.29 grams.

P.S. Notice I rounded everything to five figures. This is standard in chemistry and should be followed.

Answer 3

It depends on the element. One mole is 6.02 × 1023 atoms, which has a certain mass. But (for example) one hydrogen atom is going to weigh less than a lithium atom. Therefore, two samples of the two elements of 6.02 × 1023 atoms will weigh differently.

Answer 4

it depends on what element you are talking about

Answer 5

It depends on the element. One mole is 6.02

Answer 6

sugar is mainly and practically always glucose which has a chemical formula of

C6H12O6

so its formula mass is 180g/mol

so for one mole there is 180 grams

Answer 7

the no of grams reqduired for 1 mole is the atomicweight

Answer 8

It depends on the element you are using but you can find mass on the Periodic Table.
