The molar mass of Aluminium hydroxide is 78 g/mol. Therefore there are 5.12 moles in 400 grams of aluminium hydroxide.
1,99 grams of aluminum is equal to 0,0737 moles.
100,0 grams of aluminum is equivalent to 3,706 moles.
33 grams aluminum (1 mole Al/26.98 grams) = 1.2 moles of aluminum ================
10 grams aluminum (1 mole Al/26.98 grams) = 0.37 moles of aluminum ---------------------------------
Ok, this question is not complete. you would need to have a mass of aluminum to find the number of moles. Let me give you an example using 189 grams of aluminum: How many moles does 189 grams of aluminum have? the formula mass of aluminum is 27 so 27 grams of aluminum is the mass of 1 mole 189 grams of aluminum is the mass of (1/27 x 189)=7 moles
4,12 grams aluminum sulfate is equivalent to 0,012 moles (for the anhydrous salt).
34,2 grams of aluminium is equal to 1,267 moles.
15.8 grams of C6H12O6 is equivalent to 0.087 moles.
98,3 molecules of aluminum hydroxide Al(OH)3 is equivalent to 16,323.10e-23 moles.
It is 25 moles of Sodium Hydroxide (;
9 grams aluminum (1 mole Al/26.98 grams) = 0.3 moles aluminum ==============
The answer is 3.97 moles.
0,27 moles of calcium is equivalent to 10,82 grams.
Because the atomic mass of aluminum is 26.99, this means that there are 26.99 grams of aluminum in one mole. For 3 moles multiply 26.99 by 3 = 80.97grams.
Moles = mass in grams / atomic weight So moles in 15.01 g of Ar = 15.01 / 39.948 = 0.38 moles
10g/27grams/mole = .37 moles
4.35 moles Al × 26.98 grams/mole = 117 grams Al
4 moles aluminum (26.98 grams/1 mole Al) = 107.92 grams aluminum ---------------------------------- ( which, coincidentally, is the mass of 1 mole silver )
You need 0,133 mol aluminium hydroxide.
100 grams of carbon dioxide contain 2,27 moles.
5 grams NaOH (1 mole NaOH/39.998 grams) = 0.125 moles sodium hydroxide ( could call it 0.1 mole ) ========================================
That is aluminum hydroxide and as a polyatomic ion hydroxide needs to be in parenthesis. Thus; Al(OH)3 This shows aluminum's 3+ oxidation state and the three matching hydroxides 1- state. 42 grams Al(OH)3 ( 1 mole Al(OH)3/78.004 grams) = 0.538 moles Al(OH)3 As significant figures require; 0.54 moles Al(OH)3
21.99 grams H2O (1mol H2O/18.016 grams) = 1.221 moles H2O
4,5 g of copper is equivalent to 0,0708 moles.
0,27 moles of calcium contain 10,82 g calcium.
