Transcript text: 100 Un container per il trasporto delle merci, che ha un volume di $3,83 \times 10^{7} \mathrm{~cm}^{3}$ e una massa di $2,45 \times 10^{6} \mathrm{~g}$, viene riempito con $1,525 \times 10^{7} \mathrm{~g}$ di merce.
Calcola la densità media del container pieno in $\mathrm{g} / \mathrm{cm}^{3}$.
\[
\left[4,62 \times 10^{-1} \mathrm{~g} / \mathrm{cm}^{3}\right]
\]
Solution
Solution Steps
Step 1: Identify Given Values
Volume of the container (\(V\)): \(3.83 \times 10^7 \, \text{cm}^3\)
Mass of the empty container (\(m_{\text{container}}\)): \(2.45 \times 10^6 \, \text{g}\)
Mass of the goods (\(m_{\text{goods}}\)): \(1.525 \times 10^7 \, \text{g}\)
Step 2: Calculate Total Mass
The total mass (\(m_{\text{total}}\)) is the sum of the mass of the empty container and the mass of the goods:
\[ m_{\text{total}} = m_{\text{container}} + m_{\text{goods}} \]
\[ m_{\text{total}} = 2.45 \times 10^6 \, \text{g} + 1.525 \times 10^7 \, \text{g} \]
\[ m_{\text{total}} = 1.77 \times 10^7 \, \text{g} \]
Step 3: Calculate Density
Density (\(\rho\)) is defined as mass per unit volume:
\[ \rho = \frac{m_{\text{total}}}{V} \]
\[ \rho = \frac{1.77 \times 10^7 \, \text{g}}{3.83 \times 10^7 \, \text{cm}^3} \]
\[ \rho \approx 0.462 \, \text{g/cm}^3 \]
Final Answer
The average density of the filled container is \(4.62 \times 10^{-1} \, \text{g/cm}^3\).
