Answer:
Explanation:
1. Density from mass and volume
2. Volume from density and mass
3. Mass from density and volume
4. Density by displacement
Volume of water + object = 24.6 mL
Volume of water =<u> 12.8 mL</u>
Volume of object = 11.8 mL
Your drawing showing water displacement using a graduated cylinder should resemble the figure below.
The reserve of a fossil fuel might be increased if mining or extraction techniques improve so that more of fuel can be extracted for a profit
For this problem we use the Avogadro's number which is an empirical value that relates the number of particles to the number of moles. Its approximated value is 6.022×10²³ atoms/mole. The solution is as follows:
4.40×10²⁴ aluminum atoms * 1 moles/6.022×10²³ atoms = 7.306
Thus, there are 7.306 moles of aluminum.
