Answer:

876.672 g

Explanation:

Data given:

moles of antimony (Sb) =7.20  mol

Molar mass of Sb= 121.76 g

Mass in grams of Sb

Formula to be used

                      no. of moles = mass in grams / molar mass

For antimony (Sb) we can write as

        no. of moles of Sb = mass in grams of Sb / molar mass of Sb

Rearrange above equation

    mass in grams of Sb = no. of moles of Sb x molar mass of Sb . . . . . . .(1)

Put values in above formula (1)

 mass in grams of Sb = 7.20 mol x 121.76 g/mol

mass in grams of Sb = 876.672 g

(a) What characteristic functional group do you expect to see in the IR spectrum, that is indicative of eugenol? (b) What wavenu
Darina [25.2K]

Answer:

a) The functional group that will be evident in the IR spectrum is the OH group.

b) OH group appears between 3200-3600 cm⁻¹

c) An important impurity that have the same functional group is water.

Explanation:

Eugenol is a chemical substance that consist in a benzene that have in 1 an alcohol, in position 2 a methyl ether and in position 4 an 1-propene bonded by the terminal alkyl carbon.

a) Having this in mind, the functional group that will be evident in the IR spectrum is the OH group.

b) This OH group appears between 3200-3600 cm⁻¹

c) An important impurity that have the same functional group is water. When you have water in your sample a big signal will appear in this zone and it is possible that overlapes the OH signal of eugenol.

I hope it helps!

How many molecules are in 3.50 moles of H2O<br>​
Debora [2.8K]

Answer:

2.11 x 10²⁴ molecules.

Explanation:

  • <em>It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).</em>

<em><u>Using cross multiplication:</u></em>

1.0 mole of H₂O contains → 6.022 x 10²³ molecules.

3.5 mole of H₂O contains → ??? molecules.

∴ 3.5 mole of H₂O contain = (3.5 mol)(6.022 x 10²³) = 2.11 x 10²⁴ molecules.
