1. The mass of 6.45 x 1022 atoms C​
Fed [463]

Answer:

\large \boxed{\text{1.29 g}}

Explanation:

We must convert atoms of C to moles of C and then to grams of C.

1. Convert atoms to moles

\text{Moles of C} = 6.45 \times10^{22}\text{ atoms C} \times \dfrac{\text{1 mol C}}{6.022 \times\ 10^{23} \text{ atoms C}} = \text{0.1071 mol C}

2. Convert moles to grams

\text{Mass of C} = \text{0.1071 mol C} \times \dfrac{\text{12.01 g C}}{\text{1 mol C}} = \text{1.29 g C}\\\text{The mass of C is $\large \boxed{\textbf{1.29 g}}$}
