a 10-liter sample of one type of crude oil has a mass of 8.20kg. What i the density?
If this oil spilled on the ocean's surface, would it sink or float? explain answer in terms of density.
density = mass divided by volume. volume is the 10 liters and mass is the 8.20 kg.
you take it on from there.
AND the smaller the density, the more it will float, the larger the density, the more it will sink. so if the density of the crude oil is smaller than the water, it will float. the density of water is 1, now find the density of crude oil with the equation i have just given you.
A 56 g sample of peanut oil has a volume of 60.9 cm³. Calculate the density of the peanut oil. Remember to use the correct number of significant digits in your answer.
To find the density of the crude oil, we can use the equation:
Density = Mass / Volume
Given that the mass of the 10-liter sample is 8.20 kg, we can plug these values into the equation to calculate the density:
Density = 8.20 kg / 10 L
Now we need to convert liters to cubic meters, as the SI unit for volume is cubic meters. Since 1 liter is equal to 0.001 cubic meters, we can multiply the volume by 0.001 to convert it:
Density = 8.20 kg / (10 L x 0.001 m^3/L)
Simplifying the equation gives us:
Density = 820 kg / 0.01 m^3
Therefore, the density of the crude oil is 820 kg/m^3.
Now, to determine whether the oil would sink or float on the ocean's surface, we need to compare the density of the oil to the density of seawater.
The average density of seawater is approximately 1025 kg/m^3.
If the density of the crude oil is less than the density of seawater, it will float. On the other hand, if the density of the crude oil is greater than the density of seawater, it will sink.
In this case, the density of the crude oil (820 kg/m^3) is less than the density of seawater (1025 kg/m^3), so the crude oil would float on the ocean's surface.
This is because an object will float in a fluid if its density is less than the fluid's density. When the density of an object is less than that of the fluid, the upward buoyant force exerted by the fluid is greater than the downward force due to gravity on the object, resulting in the object floating.
