A piece of wood has a mass of m1 grams and a volume of V1 cubic centimeters. A second piece of wood has the same density ρ and a volume of V2. What is the mass, in grams, of the second piece of wood?
Q. A piece of wood has a mass of m1 grams and a volume of V1 cubic centimeters. A second piece of wood has the same density ρ and a volume of V2. What is the mass, in grams, of the second piece of wood?
Identify values and formula: Identify the known values and the formula for density. Density is mass divided by volume. The first piece of wood has a known mass m1 and volume V1, and the second piece of wood has an unknown mass m2 and a known volume V2. The density D for both pieces of wood is the same. Density formula: D=V1m1=V2m2
Calculate first piece density: Calculate the density of the first piece of wood using its mass and volume.Since the mass and volume of the first piece of wood are not given numerically, we cannot calculate the actual density. However, we can express the density in terms of the given variables.Let's denote the mass of the first piece of wood as m1 grams and its volume as V1 cubic centimeters.Density of the first piece of wood: D=V1m1
Express second piece mass: Express the mass of the second piece of wood in terms of its volume and the density.Using the density formula, we can express the mass of the second piece of wood m2 as follows:m2=D×V2Since D=V1m1, we can substitute this into the equation for m2:m2=(V1m1)×V2
Calculate second piece mass: Since the problem does not provide numerical values for m1, V1, or V2, we cannot calculate the exact mass of the second piece of wood. We need these values to proceed with the calculation.Without numerical values, we cannot provide a numerical answer for the mass of the second piece of wood (m2).
