I don't know how to solve this​
Misha Larkins [42]

For the first part, use the question M=mol/vol (liters)

To do this, you have the given 1.6 M solution

divide the 360g by the molar mass of ethanol (44.07) to get moles

360/44.07=8.16 mol

so

1.6M = 8.16 mol/x vol

volume: 5.1 Liters

Which hybrid orbitals overlap to form the sigma bonds between the indicated atoms in xanthine?
arsen [322]

The highlighted atoms have sp2 - sp3 hybridization. The highlighted atoms are carbon and nitrogen as shown.

The structure of Xanthine is shown in the image attached to this answer. The indicated atoms are Carbon and nitrogen as shown. Let us remember that hybridization has to do with the mixing of atomic orbitals to form appropriate hybrid orbitals that are suitable for overlap with orbitals of other atoms.

The highlighted carbon atom is sp2 hybridized because it has a carbon nitrogen double bond while the highlighted nitrogen atom is sp3 hybridized. Therefore, the highlighted atoms have sp2 - sp3 hybridization.

How many moles of hydrogen atoms are there in one mole of C6H12O2
zvonat [6]

In 1 molecule of the compound C₆H₁₂O₂ there are 12 moles of hydrogen atoms

<h3>Further explanation</h3>

Given

C₆H₁₂O₂ compound

Required

moles of Hydrogen

Solution

In a compound, there is a mole ratio of the constituent elements.

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

In the C₆H₁₂O₂ compound, there are 3 forming elements: C, H and O

The number of each element is indicated by its subscript

C: 6 moles

H = 12 moles

O = 2 moles
