Asked by Claire
The diameter of a hydrogen atom is about 5×10^-11 meter. Suppose 8.4×10^8 hydrogen atoms were arranged side by side in a straight line. Multiply these numbers to find the length of this line of atoms. What is the length in scientific notation?
42×10^−3 meter
0.042 meter
4.2×10^−2 meter
4.2×10^−3 meter
42×10^−3 meter
0.042 meter
4.2×10^−2 meter
4.2×10^−3 meter
