Final answer:
The mass of 10.0 cm3 of aluminum foil with a density of 0.789 g/cm3 is found to be 7.89 grams using the formula Mass = Density × Volume and considering significant figures.
Step-by-step explanation:
To calculate the mass of 10.0 cm3 of aluminum foil with a density of 0.789 g/cm3, you can use the formula:
Mass = Density × Volume
Plug in the values for the density and volume:
Mass = (0.789 g/cm3) × (10.0 cm3)
Mass = 7.89 g
Therefore, the mass of 10.0 cm3 of aluminum foil is 7.89 grams. Remember to use proper significant figures. Since the density was given to three significant figures and the volume to three significant figures as well, our mass will be reported to three significant figures.
