Calculate the actual mass of one atom of carbon if 12g of cardron contains one mole of carbon.

2.0 × 10⁻²³ g C

General Formulas and Concepts:

Chemistry - Atomic Structure

Using Dimensional AnalysisAvogadro Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Explanation:

Step 1: Define

1 atom C

Step 2: Identify Conversions

Avogadro Number

Molar Mass of C - 12.01 g/mol

Step 3: Convert

= 1.99435 × 10⁻²³ g C

Step 4: Check

We are given 2 sig figs. Follow sig fig rules and round.

1.99435 × 10⁻²³ g C ≈ 2.0 × 10⁻²³ g C

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
