I para realizar un receta casera de bizcocho se necesitan 100 gramos de azúcar, calcula los moles a los que equivale y el número de moléculas de sacarosa.

The complete question is as follows: I want to make a homemade cake recipe you need 100 grams of sugar, calculate the moles to which it is equivalent and the number of molecules of sucrose.

In 100 grams of sugar there are 0.292 moles and the number of molecules of sucrose are .

Explanation:

Given: Mass = 100 g

Molar mass of sugar = 342.3 g/mol

As number of moles is the mass of substance divided by its molar mass.

Hence, moles of sucrose are calculated as follows.

According to mole concept, 1 mole of every substance contains molecules.

Hence, the number of molecules present in 0.292 mol are calculated as follows.

Thus, we can conclude that in 100 grams of sugar there are 0.292 moles and the number of molecules of sucrose are .

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
