The approximate atomic weight (not molar mass) of aluminium is 26,98 amu.
The value after IUPAC Table of atomic weights is 26,981 538 57(1).
The molar mass of dioxane is approximately 88.11 grams per mole.
The molar mass of benzene is 78 g.
The formular you need is M = n/m (molar mass = amount of substance/mass), or n = m/MAluminium has a molar mass of 26.982 g/mol. The given mass is 3 grams. Therefore:n(Al) = 3g / (26.982g/mol) = 0.11mol
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.00 moles Al × (27.0 grams) = 54.0 grams Al
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.91 moles Al × (27.0 grams) = 78.6 grams Al
The molar mass of anhydrous aluminum chloride is 133,34 grams.
The molar mass of dioxane is approximately 88.11 grams per mole.

116.17 grams (NH4)2SO3
Aluminum has a molar mass of 26.98 you just have to look on your periodic table
The molar mass aluminum chloride is 133,34 g (for the anhydrous salt).
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
The molar mass of benzene is 78 g.
