the density of 400cm³ of palm oil was 0.9gcm before frying, if the density of the oil was 0.6gcm^-³ alter frying, assuming no loss of oil due to spilling, its new volume was?
no loss means mass is constant.
mass=density*volume
.9*400=..6*V
To find the new volume of the palm oil after frying, we can use the equation:
Density = Mass / Volume
Before frying, the density of the oil was 0.9 g/cm³. We are given the initial volume as 400 cm³. We can rearrange the equation to solve for the initial mass:
Mass = Density * Volume
Mass = 0.9 g/cm³ * 400 cm³
Mass = 360 g
After frying, the density of the oil is given as 0.6 g/cm³. Let's denote the new volume as V2. We can use the same equation to find the new mass:
Mass = Density * Volume
360 g = 0.6 g/cm³ * V2 cm³
Now, we can rearrange the equation to solve for V2:
V2 cm³ = 360 g / 0.6 g/cm³
V2 cm³ = 600 cm³
Therefore, the new volume of the palm oil after frying is 600 cm³.
To solve this problem, you need to use the concept of density and the formula relating density, mass, and volume.
Density is defined as the mass of an object divided by its volume. The formula to calculate density is:
Density = Mass / Volume
Given information:
Density before frying = 0.9 g/cm³
Density after frying = 0.6 g/cm³
Initial volume (before frying) = 400 cm³
To find the new volume after frying, rearrange the density formula as follows:
Volume = Mass / Density
1. Calculate the initial mass:
Initial mass = Density before frying * Initial volume
Initial mass = 0.9 g/cm³ * 400 cm³ = 360 g
2. Use the initial mass and the density after frying to find the new volume:
New volume = Mass / Density after frying
New volume = 360 g / 0.6 g/cm³ = 600 cm³
Therefore, the new volume of palm oil after frying, assuming no loss of oil due to spilling, is 600 cm³.
