Calculate the number of moles in a 102 gram sample of AX
AX=8.5 grams / mol
102 / 8.5 = 12 mols
To calculate the number of moles in a sample of AX, you can use the formula:
moles = mass / molar mass
First, let's find the molar mass of AX. Since A = 3.2 and X = 5.3, we can add their molar masses to get the molar mass of AX.
The molar masses of A and X are approximately:
A = 3.2 g/mol
X = 5.3 g/mol
Next, add the molar masses:
Molar mass of AX = Molar mass of A + Molar mass of X
= 3.2 g/mol + 5.3 g/mol
To find the molar mass of AX, add 3.2 and 5.3:
Molar mass of AX = 8.5 g/mol
Now we have the molar mass of AX, which is 8.5 g/mol.
Finally, divide the mass of the sample by the molar mass to calculate the number of moles:
moles = mass / molar mass
= 102 g / 8.5 g/mol
To find the number of moles in a 102 gram sample of AX, divide 102 by 8.5:
moles = 12
Therefore, there are 12 moles in a 102 gram sample of AX.
To calculate the number of moles in a sample of a substance, we need to use the formula:
Number of Moles = Mass of Substance / Molar Mass
In this case, we are given that the mass of the sample (AX) is 102 grams. To find the molar mass, we need to know the atomic masses of the elements involved.
Given:
A = 3.2 (atomic mass)
B = 16.0 (atomic mass)
X = 5.3 (atomic mass)
To find the molar mass of AX, we need to add the atomic masses of A and X together:
Molar Mass of AX = Atomic Mass of A + Atomic Mass of X
Molar Mass of AX = 3.2 + 5.3
Now, we can calculate the number of moles:
Number of Moles = Mass of Substance / Molar Mass
Number of Moles = 102 grams / (3.2 + 5.3)
After solving this equation, we will get the number of moles in the 102 gram sample of AX.
