How would I calculate the number of moles of AgNO3?
I have .0025L
but don't I need the Molarity? I have no idea how to find that.
Not enough info. What do you have .0025L of? Do you have any other info?
mols = M x L = ?
But without M it can't be done unless there are other numbers.
To calculate the number of moles of a substance, you need to know both the volume and the concentration. The concentration of a substance is often given in terms of Molarity, which is defined as the number of moles of solute per liter of solution.
In order to calculate the number of moles of AgNO3, you will need to know the Molarity (M) of the solution containing AgNO3.
If you do not have the Molarity, you will need to find it using the available information. Here's how you can do that:
1. Determine the mass of AgNO3: Look for the molecular weight of AgNO3. The atomic weights of silver (Ag), nitrogen (N), and oxygen (O) are 107.87 g/mol, 14.01 g/mol, and 16.00 g/mol, respectively. Calculate the molecular weight of AgNO3 by adding the atomic weights of the individual atoms: (1 x Ag) + (1 x N) + (3 x O).
2. Convert the volume from liters to moles: Multiply the volume given (0.0025 L in your case) by the Molarity (M) to obtain moles. This will give you the number of moles of AgNO3 in the given volume.
To summarize:
Moles of AgNO3 = Volume (in liters) x Molarity (M)
In this case, since you mentioned that you do not have the Molarity, you would need to find it as explained above.
