1. Weight of a carbon atom: 1.99 \times 10^{-26}
2. Weight of a helium atom:6.65 \times 10^{-27}
3. Divide the weight of the carbon atom by the weight of the helium atom:
\frac{1.99 \times 10^{-26}}{6.65 \times 10^{-27}}
4. Calculate the ratio:
\frac{1.99}{6.65} \times \frac{10^{-26}}{10^{-27}} = \frac{1.99}{6.65} \times 10^{1}
5. Simplify the fraction:
\frac{1.99}{6.65} \approx 0.2992
6. Multiply by10^{1}
0.2992 \times 10 = 2.992
7. Round to the nearest whole number:
\approx3
Thus, an atom of carbon is approximately3
