I need to figure out how many moles are in 16.0 grams of sulfur dioxide.
I know that sulfur dioxide is SO2 so do I do I do? Do I find the molar mass first?
Wow.. that came out weird. I meant to say what do I do. Hmm. Anyways, I found the molar mass and it's 64.1. But I don't know what to do next
#mols = g/molar mass.
Yes, you are on the right track. To determine the number of moles in a given mass of a substance, you need to know its molar mass first. The molar mass is the mass of one mole of a substance and is expressed in grams per mole (g/mol).
To find the molar mass of sulfur dioxide (SO2), you need to add up the individual atomic masses of sulfur (S) and oxygen (O). The atomic mass of sulfur is approximately 32.07 g/mol, and each oxygen atom has an atomic mass of approximately 16.00 g/mol.
Therefore, you can calculate the molar mass of SO2 as follows:
Molar mass of SO2 = (atomic mass of sulfur) + 2 x (atomic mass of oxygen)
Molar mass of SO2 = (32.07 g/mol) + 2 x (16.00 g/mol)
Molar mass of SO2 = 64.07 g/mol
Now that you know the molar mass of SO2 is 64.07 g/mol, you can use this information to determine the number of moles in 16.0 grams of SO2.
To calculate the number of moles, you can use the formula:
Number of moles = Mass / Molar mass
Plugging in the given mass of sulfur dioxide (16.0 grams) and the molar mass of SO2 (64.07 g/mol), the calculation looks like this:
Number of moles = 16.0 g / 64.07 g/mol
By dividing 16.0 grams by 64.07 grams per mole, you will get the number of moles of sulfur dioxide.
