To find the number of moles in 10g of Cu(NO3)2, we need to use the formula:
moles = grams / molar mass
Step 1: Determine the molar mass of Cu(NO3)2.
To calculate the molar mass of Cu(NO3)2, we need to add up the atomic masses of all the elements in one molecule of Cu(NO3)2.
The atomic mass of Cu (Copper) = 63.55 g/mol
The atomic mass of N (Nitrogen) = 14.01 g/mol
The atomic mass of O (Oxygen) = 16.00 g/mol
Since there are two Nitrogen atoms and six Oxygen atoms in one molecule of Cu(NO3)2, we multiply the atomic masses accordingly.
Molar mass of Cu(NO3)2 = (1 * Cu) + (2 * N) + (6 * O)
= (1 * 63.55) + (2 * 14.01) + (6 * 16.00)
= 63.55 + 28.02 + 96.00
= 187.57 g/mol
Therefore, the molar mass of Cu(NO3)2 is 187.57 g/mol.
Step 2: Substitute the values into the formula.
moles = grams / molar mass
moles = 10g / 187.57 g/mol
Step 3: Calculate the moles.
moles = 0.0532 mol
Therefore, there are 0.0532 moles in 10g of Cu(NO3)2.
