First you take your compound AlCl3 and find the molar mass
26.98gAl+(3)35.45gCl= 133.33gAlCl3
Then you convert moles to grams
5molAlCl3x1g(over)1molx133.33g(over)1g=666.65gAlCl3
if you follow the rule of Significant Figures, 5mol has one significant figure (digit) so your answer needs to have 1 digit
700gAlCl3
33 grams aluminum (1 mole Al/26.98 grams) = 1.2 moles of aluminum ================
how many grams are in a mole of soda cans? show work
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
26.98 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.
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 ---------------------------------
how many grams are in a mole of soda cans? show work
16. 2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum -------------------------------------------
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
9 grams aluminum (1 mole Al/26.98 grams) = 0.3 moles aluminum ==============
Aluminum chloride has a formula of AlCl3, and its molecular weight is the sum of the atomic weights of its atoms. Al has a mass of 27.0, and Cl, 35.5. So we add the masses of Al (27.0) and the chlorides (3x34.5=106.5) to get a molecular weight of 133.5 grams per mole of AlCl3. If we have 4177g and divide it by 133.5g/mole, we get 31.30 moles.
26.98 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.
the mass of one mole od aluminum is 65.2 grams
I assume you mean grams of aluminum. 4.1 X 10 -5 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 9.2 X 1017 atoms of aluminum ------------------------------------------
72.0 grams NaCl (1 mole NaCl/58.44 grams) = 1.2 moles of sodium chloride
