How many moles of compound are ther in 3.82 g SO2
Is your high school really the name of your subject?
What concerns me is that you posted your high school name, and your real name. Hasn't your momma warned you about that? It is not just little girls who have to worry about internet dangers.
Divide the mass of SO2 by the mole mass in grams of SO2.
To determine the number of moles of a compound, we need to use the molar mass of the compound. In this case, we are given the mass of sulfur dioxide (SO2), which is 3.82 grams.
1. First, find the molar mass of SO2:
- The atomic mass of sulfur (S) is approximately 32.07 grams per mole.
- The atomic mass of oxygen (O) is approximately 16.00 grams per mole.
- Since there are 2 oxygen atoms in SO2, the total molar mass is:
Molar mass of SO2 = (2 × atomic mass of O) + atomic mass of S
= (2 × 16.00 g/mol) + 32.07 g/mol
= 32.00 g/mol + 32.07 g/mol
= 64.07 g/mol
2. Now, use the molar mass and the given mass to calculate the number of moles:
- Number of moles = Mass / Molar mass
- Number of moles = 3.82 g / 64.07 g/mol
Calculating this division:
- Number of moles = 0.0597 moles (rounded to four decimal places)
Therefore, there are approximately 0.0597 moles of SO2 in 3.82 grams.
