How many moles of molecules are in 10 g of aspartame?

The moles of molecules are in 10 g of aspartame - 0.034 × 10¹⁹

The number of molecules of a given mass of a substance using the molar mass of the substance and Avogadro's constant, 6.022 × 10²³

The number of moles =

=

= 0.034 × 10 ⁻⁵ mole

Using Avogadro's constant, we can convert this value to molecules as so:

= 0.034 × 10 ⁻⁵ (6.022 × 10²³)

= 0.034 × 10¹⁹

Thus, the moles of molecules are in 10 g of aspartame - 0.034 × 10¹⁹

Explanation:

Data Given:

mass of aspartame = 10 g

molecules of aspartame = ?

Solution

First we calculate no. of moles of 10 g aspartame

For which mole formula will be used

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

Formula of aspartame:

C₁₄H₁₈N₂O₅

So,

The molar mass of aspartame (C₁₄H₁₈N₂O₅) will be

molar mass of C₁₄H₁₈N₂O₅ = 14(12) + 18(1) + 2(14) +5(16)

molar mass of C₁₄H₁₈N₂O₅ = 168 + 18+ 28 + 80

molar mass of C₁₄H₁₈N₂O₅ = 294 g/mol

put values in equation 1

          no. of moles = 10 g / 294 g/mol

          no. of moles = 0.034 mol

now we will calculate no. of molecules

Formula will be used

           no. of moles = no. of molecules / Avogadro's number

Rearrange the above equation:

no. of molecules = no. of moles x Avogadro's number . . . . . (2)

Where

Avogadro's number = 6.022 x 10²³

Put values in equation 2

           no. of molecules =0.034 mol x 6.022 x 10²³ (molecules/mol)

           no. of molecules = 2.0475 x 10²²

So,

There are 2.0475 x 10²² molecules are in 10 grams of aspartame that is 0.034 moles of aspartame.

So,  in turn its 0.034 moles of molecules are in 10 g of aspartame.

s too much pool water may lead to chlorine poisoning. the concentration of chlorine in public drinking water is extremely low and not harmful to human health. sooo yeahh

explanation:

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
