How many molecules are in 2.0 grams of aluminum chloride?
To determine the number of molecules in 2.0 grams of aluminum chloride, first calculate the molar mass of aluminum chloride (AlCl3). The molar mass is 133.34 g/mol. Next, convert the given mass (2.0 g) to moles using the molar mass. Finally, use Avogadro's number (6.022 x 10^23) to find the number of molecules.
What element has a molar mass of 26.98 grams?
Aluminum has a molar mass of 26.98 you just have to look on your periodic table
How many grams are in 5 mole of aluminum chloride?
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
What is the formula mass of a molecule of aluminum chloride if the mass number of aluminum is 27 and chlorine is 35?
The molar mass of aluminum (Al) is 27 g/mol and chlorine (Cl) is 35 g/mol. Aluminum chloride (AlCl3) has one aluminum atom and three chlorine atoms. Therefore, the formula mass (or molar mass) of aluminum chloride is 27 (Al) + 3(35) (3Cl) = 106 g/mol.
Converting between moles of aluminum chloride and grams of aluminum chloride is most similar to what calculations?
Converting between moles of aluminum chloride and grams of aluminum chloride is most similar to converting between eggs and dozens of eggs. Just like one dozen equals 12 eggs, one mole of aluminum chloride contains Avogadro's number of particles (6.022 x 10^23) which corresponds to its molar mass in grams.
The molar mass of aluminum chloride is?
The molar mass of aluminum chloride (AlCl3) is approximately 133.34 g/mol.

What is the molar mass of aluminum chloride?
The molar mass aluminum chloride is 133,34 g (for the anhydrous salt).
Mass of aluminum chloride?
The molar mass of aluminum chloride (AlCl3) is approximately 133.34 g/mol. To find the mass of aluminum chloride, you would need to know the amount of substance (in moles) and then use the molar mass to calculate the mass. For example, if you had 2 moles of aluminum chloride, the mass would be 2 moles * 133.34 g/mol = 266.68 grams.

Now assume you measure out exactly 2.0 ml of aluminum chloride into a third test tube How many moles of aluminum chloride are in the tube?
To calculate the number of moles of aluminum chloride in the test tube, you need to know the molar mass of aluminum chloride (AlCl3). The molar mass of AlCl3 is 133.34 g/mol. Given that you have 2.0 ml of AlCl3, you will need to convert this volume to grams using the density of AlCl3. Finally, you can calculate the moles using the molar mass.
How many grams of aluminum chloride can be made from 67.0 grams of aluminium and excess hydrochloric acid?
To determine the amount of aluminum chloride that can be produced, you need to consider the stoichiometry of the reaction between aluminum and hydrochloric acid. The balanced equation is 2Al + 6HCl → 2AlCl3 + 3H2. From the equation, 2 moles of aluminum produce 2 moles of aluminum chloride. You can use the molar mass of aluminum chloride to convert moles to grams.
What is the mass of 1 mole aluminum?
The molar mass of aluminum is approximately 26.98 g/mol, so the mass of 1 mole of aluminum is 26.98 grams.
How many grams of aluminium are contained in 100.0 g of aluminum chloride AlCl3?
The gram atomic mass of aluminium is 26.9815, and the gram atomic mass of chlorine is 35.453. The formula shows that there are three chlorine atoms for each aluminium atom in the compound. Therefore, the mass fraction of aluminium in the compound is 26.9815/[26.9815 + 3*(35.453)] or about 0.20235004, and the grams of aluminium present are 20.24, to the justified number of significant digits. _______________________________________ *An exact integer.
