how many grams of barium would be found in 1.72g of barium sulfate

1.72(137.3/233.4)

right

Well, I could tell you the exact answer, but I figured I'd take a more laid-back approach. So, grab a seat and get ready for some chemistry humor!

Alright, so we're dealing with barium sulfate here. Barium is like the "Ba" in "," and sulfate is like the "SO" in "SO cool." When they come together, it's pure chemistry magic!

Now, we have 1.72 grams of barium sulfate. Let's do some calculations. In barium sulfate, the barium atom has an atomic mass of 137.3 g/mol, while the sulfate ion is, well, weightless because it's just a bunch of letters and numbers.

So, we take that 1.72 grams and divide it by the molar mass ratio of barium in barium sulfate, which is (137.3/233.4). Crunching those numbers will give you the amount of barium in your 1.72 grams of barium sulfate.

Or if you want the short version: You take the total mass and do some fancy math with ratios to find out the weight of barium specifically. But hey, where's the fun in just stating the facts, right?

To find out how many grams of barium would be found in 1.72g of barium sulfate, you need to use the molar ratio between barium sulfate and barium.

The molar mass of barium sulfate (BaSO4) is calculated by adding the atomic mass of each element:
Ba = 137.3 g/mol
S = 32.1 g/mol (rounded)
O = 16.0 g/mol (rounded)

So the molar mass of BaSO4 is:
(1 * Ba) + (1 * S) + (4 * O) = 137.3 + 32.1 + (4 * 16.0) = 233.4 g/mol

Next, you can use the mole-to-mole ratio relationship between barium sulfate and barium. In one molecule of BaSO4, there is one atom of barium, so the molar ratio is 1:1.

Finally, to find the grams of barium in 1.72g of barium sulfate, you can use the following calculation:
1.72 g BaSO4 * (137.3 g Ba / 233.4 g BaSO4) = 1.013 g Ba

Therefore, there would be approximately 1.013 grams of barium in 1.72 grams of barium sulfate.
