Which has more individual molecules 1 mole of sugar or 1 mole of salt?
The mole is the translation factor between weights and numbers of particles. One mole of any substance weighs a number of grams that is equal to the atomic or molecular weight of that substance. Thus, 2.05 oz (58.45 g) of salt and 11.98 oz (342.3 g) of sugar contain the same number of molecules: 6.02 × 1023.
Which mole has the largest mass?
Finally, you know that 1 mole of a molecular substance must contain 6.022⋅1023 molecules of that substance. Therefore, sample A will have the larger mass because it contains the biggest number of oxygen molecules.
What is the mass of one mole of salt?
Every element has a different molar mass. For example, one mole of sodium (Na) has a mass of 22.9898 g/mol.
Does salt and sugar have the same mass?
Here’s why: Salt is about 25% more dense than sugar. Therefore a teaspoon of salt weighs more than a teaspoon of sugar by almost 25%. Your dissolving test would not be accurate because you would be starting out with a larger mass of salt than sugar.
How many grams of sugar does it take to start with one mole of carbon?
Sugar = let us assume it is glucose = C6H12O6 ⇒ C = 12 grams per C, and H = 1 gram per H, and O = 16 grams per O. C6H12O6 = (6 x 12) + (12 x 1) + (6 x 16) = 180 grams per mole.
How many grams are in 1 mole of glucose?
180 g.
a mole is the quantity of a substance whose weight in grams is equal to the molecular weight of the substance. Thus 1 mole of glucose weighs 180 g.
How to calculate the molar mass of sugar?
Molar Mass, Molecular Weight and Elemental Composition Calculator Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of (sugar)C12H22O11 is 342.2965 g/mol
How to calculate the mole mass of NaCl?
Molar mass of NaCl = atomic mass of Na (22.99 amu) + the atomic mass of Cl (35.45 amu) 22.99 + 35.45 = 58.44 amu One mol of 23 NaClformulas) (6.02mass hasx10of 58.44a g. Toobtain one mole of copper 23 atoms), atoms (6.02 x 10 weigh out 63.55 g copper. PT 4
How many atoms are in a mole of carbon-12?
The mole (or mol) represents a certain number of objects. SI def.: the amount of a substance that contains the same number of entities as there are atoms in 12 g of carbon-12. Exactly 12 g of carbon-12 contains 6.022 x 10 23 atoms. 1 mole contains 6.022 x 1023
