To estimate the density of hydrogen, which is given as 0.0000899 g/cm³, we can write this number in scientific notation:
0.0000899 g/cm³ = 8.99 x 10^-5 g/cm³
Now we can compare this with the provided options:
A. 8 x 10^-4 g/cm³ (which is 0.0008 g/cm³, much too high)
B. 9 x 10^-5 g/cm³ (which is 0.00009 g/cm³, reasonably close)
C. 8 x 10^-5 g/cm³ (which is 0.00008 g/cm³, also reasonably close)
D. 9 x 10^-4 g/cm³ (which is 0.0009 g/cm³, also much too high)
Among the options, B (9 x 10^-5 g/cm³) and C (8 x 10^-5 g/cm³) are reasonable estimates of the density of hydrogen. However, the option that is the closest to the given density of 0.0000899 g/cm³ is:
**B. 9 x 10^-5 g/cm³**
0.0000899 g/cm³ = 8.99 x 10^-5 g/cm³
Now we can compare this with the provided options:
A. 8 x 10^-4 g/cm³ (which is 0.0008 g/cm³, much too high)
B. 9 x 10^-5 g/cm³ (which is 0.00009 g/cm³, reasonably close)
C. 8 x 10^-5 g/cm³ (which is 0.00008 g/cm³, also reasonably close)
