How do you find the molar mass of an anhydrous salt?

How do you find the molar mass of an anhydrous salt?

Determine the molar mass of the anhydrous salt using the periodic table. The periodic table lists the molar mass of each element. Multiply the molar mass of each element in your compound by the number of times it appears in your compound to get the molar mass of the compound.

What is the molar mass of the anhydrous compound?

245 g/mol
The molar mass of the anhydrous compound (AC) is 245 g/mol.

What is the formula of anhydrous salt?

This ratio is expressed in the formula of the compound. For example, if heating some hydrated copper (II) sulfate gave off 0.060 moles of water, and left behind 0.012 moles of anhydrous copper (II) sulfate (CuSO4), then the ratio of water to anhydrous salt is 5:1, and the formula would be written as CuSO4•5H2O.

What is an anhydrous salt?

Anhydrous salts are compounds that have no water molecules attached to the salt molecules. We use this term mostly when water of crystallization removes from hydrated salts. Therefore, the term anhydrous refers to a dry salt.

What is the mass of anhydrous salt?

When a 1.000 g sample of CuSO4• 5 H2O(s) was heated so that the waters of hydration were driven off, the mass of the anhydrous salt remaining was found to be 0.6390 g.

What is the mass of the remaining anhydrous salt?

Upon heating, the mass of the anhydrous salt that remains is 0.256 grams.

What is the molar mass of the anhydrous salt FeSO4 g mol?

*100 g = 42 grams of water. That leaves 58 grams of FeSO4 The molar mass of FeSO4 is 151.95 grams/mole. Calculate the number of moles of FeSO4: 58 grams FeSO4/(151.95 g/mole FeSO4) = 0.382 moles FeSO4.

What is anhydrous formula?

nAnhydrous Solid=mAnhydrous SolidMMAnhydrous Solid. In order to determine the formula of the hydrate, [Anhydrous Solid⋅xH2O], the number of moles of water per mole of anhydrous solid (x) will be calculated by dividing the number of moles of water by the number of moles of the anhydrous solid (Equation 2.12.

What is the molar mass of anhydrous cuso4?

159.6 g/mol .

How do you find the remaining anhydrous salt?

When all hydrating water is removed, the material is said to be anhydrous and is referred to as an anhydrate. Experimentally measuring the percent water in a hydrate involves first heating a known mass of the hydrate to remove the waters of hydration and then measuring the mass of the anhydrate remaining.

What is the molar mass of anhydrous salt in grams?

Molar mass of anhydrous salt: 110. g/mol Mass of anhydrous salt: 0.908 g Number of moles of anhydrous salt remaining in the crucible: 0.00825 mol Number of moles of water lost: 0.00827 mol

What is the molecular mass of glucose molecule (C6H12O6)?

What is the molecular mass of glucose molecule (C6H12O6) is: – Chemistry Question The answer is: Molecular mass of glucose (C6H12O6) = (12 x 6 + 1 x 12 + 16 x 6 = 180). Access detailed answers to various other Science and Maths questions at BYJU’S.

How do you calculate the molar mass of KAl(SO4)2?

Step 1: Find the mass of the dry anhydrous salt show work: Final weighing – mass of pan = mass of anhydrous salt Step 2: Find the molar mass of KAl (SO4)2 and show work here Step 3: Find the moles with work shown: grams of the dry salt divided by the molar mass = moles B. Calculate the ratio of moles of H2O to moles of anhydrous KAl (SO4)2.

What is the empirical formula for anhydrous KAl(SO4)2?

Hint: if the ratio of moles of H 2 O to moles of anhydrous KAl (SO 4) 2 was 4, then the empirical formula would be: KAl (S0 4) 2 •4H 2 0. Show your work. Want to see the step-by-step answer?
