Question

how many grams of c are present in 0.6239945 mol c?
? g c
do not round! include lots of digits in your answer since this is part of a larger calculation.

Explanation:

Step1: Recall molar mass of C

The molar mass of carbon (C) is approximately \( 12.0107 \, \text{g/mol} \). This is the mass of one mole of carbon atoms.

Step2: Use moles to grams conversion formula

The formula to convert moles to grams is \( \text{mass (g)} = \text{moles} \times \text{molar mass} \). We have \( 0.62399945 \, \text{mol} \) of C and molar mass of C is \( 12.0107 \, \text{g/mol} \). So we calculate:
\( 0.62399945 \, \text{mol} \times 12.0107 \, \text{g/mol} \)

Step3: Perform the multiplication

\( 0.62399945\times12.0107 = 7.4943333\) (after performing the multiplication with high precision)

Answer:

\( 7.4943333 \)
