An empty beaker weighs 20g and when filled with a liquid weighs 65g. The volume of the liquid is found to be 25cm³. Determine the density of the liquid
Bob Pursley worked this for you earlier today.
What's the answer
To determine the density of a substance, we can use the formula:
Density = mass / volume
In this case, the mass of the liquid can be found by subtracting the weight of the empty beaker from the weight of the beaker filled with liquid.
Mass of the liquid = weight of beaker with liquid - weight of empty beaker
Mass of the liquid = 65g - 20g = 45g
Now that we know the mass of the liquid is 45g and the volume is 25cm³, we can use the formula to find the density:
Density = 45g / 25cm³
Simplifying this equation gives:
Density = 1.8 g/cm³
Therefore, the density of the liquid is 1.8 g/cm³.
