Question 5 1 pts Suppose you hold a 12-cm3 block of aluminum and a 2.0-cm3 block of brass in your two hands. Which block has more mass? O the block of aluminum has more mass the block of brass has more mass O the two blocks have the same mass O You cannot tell which block has more mass without knowing their shapes
if the density of mercury is 13.8g/cm3. calculate the
mass in kg of 2.0L of mercury
If the density of mercury is 13.8 g/cm3, calculate the mass in kilograms of 2.0 L of mercury.
The mass unit associated with density is usually grams. If the volume (in mL or cm3) is multiplied by the density (g/mL or g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3
Calculate the mass of copper in grams (density = 8.96 g/cm3) with the same volume as 100.0 grams of gold (density = 19.31 g/cm3).
Water has a density of 1.0 g/cm3. Consider two cubes, one of aluminum and one of copper. If each cube measures 10 cm along an edge, calculate the mass of each cube. physics
1) Aluminum has a density of 2.699 g/cm3, and the radius of the
