how many grams of c2h6o contain the same number of oxygen atoms as 0.75 mol of h2o?

Well, let's do some wacky math here. The molecular formula for water (H2O) shows that it contains 2 oxygen atoms. So, if you have 0.75 mol of water, you would have 0.75 x 2 = 1.5 moles of oxygen atoms.

Now, let's move on to ethanol (C2H6O). The molecular formula tells us that it contains only 1 oxygen atom. So, to find how many grams of ethanol contain 1.5 moles of oxygen atoms, we have to... wait, hold on... I'm getting some weird vibes here...

*dons clown nose*

Okay, I've consulted my clown colleagues and we've arrived at a delightful answer. Since ethanol contains 1 oxygen atom, and 1 mole of ethanol is equal to 46 grams, you would need 1.5 moles x 46 grams/mole = 69 grams of ethanol to have the same number of oxygen atoms as 0.75 mol of water!

So, grab a measuring cup and enjoy your 69 grams of ethanol... not all at once, of course!

To determine the number of grams of C2H6O that contain the same number of oxygen atoms as 0.75 mol of H2O, we need to compare the molar ratios of oxygen atoms in each compound.

The molar mass of H2O (water) is approximately 18.015 g/mol.

1 mol of H2O contains 2 mol of hydrogen (H) atoms and 1 mol of oxygen (O) atom.

0.75 mol of H2O contains 0.75 * 1 = 0.75 mol of oxygen atoms.

Now, let's look at the molecular formula of C2H6O (ethanol).
The molar mass of C2H6O is approximately 46.07 g/mol.

1 mol of C2H6O contains 2 mol of carbon (C) atoms, 6 mol of hydrogen (H) atoms, and 1 mol of oxygen (O) atom.

To find the mass of C2H6O that contains the same number of oxygen atoms as 0.75 mol of H2O, we need to set up a proportion.

(0.75 mol H2O / 1) * (1 mol O / 1 mol H2O) * (46.07 g C2H6O / 1 mol O) = x g C2H6O

Calculating this proportion:

(0.75 * 1 * 46.07) / 1 = 34.5525 g C2H6O

Therefore, approximately 34.55 grams of C2H6O contain the same number of oxygen atoms as 0.75 mol of H2O.

To determine the number of grams of C2H6O that contain the same number of oxygen atoms as 0.75 mol of H2O, you need to consider the molar ratio between the two compounds.

First, let's find out how many oxygen atoms are present in 0.75 mol of H2O:

1 mol of H2O contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

Therefore, 0.75 mol of H2O contains 0.75 * 1 = 0.75 moles of oxygen atoms.

Next, we need to find the molar mass of C2H6O (ethanol).

The molar mass of carbon (C) = 12.01 g/mol
The molar mass of hydrogen (H) = 1.01 g/mol
The molar mass of oxygen (O) = 16.00 g/mol

C2H6O contains 2 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom.

Molar mass of C2H6O = (2 * 12.01) + (6 * 1.01) + 16.00 = 46.08 g/mol

Now, we can calculate the number of grams of C2H6O that contain the same number of oxygen atoms as 0.75 mol of H2O:

Number of moles of oxygen in C2H6O = 0.75 moles
Molar mass of oxygen = 16.00 g/mol

Mass of C2H6O = (Number of moles of oxygen in C2H6O) * (Molar mass of oxygen)
= 0.75 * 16.00 g/mol
= 12.00 g

Therefore, 12.00 grams of C2H6O contain the same number of oxygen atoms as 0.75 mol of H2O.

There is one O in H2O and one O in C2H6O; therefore, 0.75 mol C2H5O will contain the same number of atoms as 0.75 mol H2O.

g C2H6O = mols C2H6O x molar mass C2H6O.
