Educated Guess Here!
Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.
The scientific notation for 8,950,000 is
8.95 × 10^6
Answer:
34.6 cm³
Explanation:
Given data
- Mass of carbon tetrachloride (m): 55.0 g
- Density of carbon tetrachloride (ρ): 1.59 g/cm³
- Volume of carbon tetrachloride (V): ?
We can determine the volume of carbon tetrachloride that the student should pour out using the following expression.
ρ = m / V
V = m / ρ
V = 55.0 g / (1.59 g/cm³)
V = 34.6 cm³
