A steel ball has a volume of 1500cm³. The density of the ball is 95g/cm³. Find the mass of the ball in kg.
The formula to calculate the mass of an object is:
Mass = Volume x Density
Given that the volume of the steel ball is 1500 cm³ and the density is 95 g/cm³, we can substitute these values into the formula to find the mass:
Mass = 1500 cm³ x 95 g/cm³
Using unit conversion, we can convert cm³ to m³ by dividing by 100^3 and g to kg by dividing by 1000:
Mass = (1500 cm³ / 100^3) x (95 g / 1000)
Simplifying this equation, we have:
Mass = (1500 x 95) / (100^3 x 1000)
Mass = 142,500 / 10^8
Mass = 0.001425 kg
Therefore, the mass of the steel ball is 0.001425 kg.
What do you use to measure the volume of a liquid
To measure the volume of a liquid, you can use various tools such as:
1. Graduated Cylinder: This is a common and precise instrument used to measure the volume of liquids. It has markings along its side that indicate the volume of liquid present.
2. Measuring Cup: Measuring cups are often used in cooking to measure the volume of liquids. They usually have markings on the side indicating different volume measurements.
3. Beaker: Beakers are commonly used in laboratories to hold and measure liquids. While they may not be as precise as graduated cylinders, they do provide a general estimate of the liquid volume.
4. Pipette: A pipette allows you to accurately measure small volumes of liquid. There are different types of pipettes, including micropipettes for measuring very small volumes.
5. Burette: A burette is a long, graduated tube with a stopcock at the bottom, used for precise volume measurements in titrations and other analytical procedures.
It's important to ensure that you choose the appropriate instrument based on the volume range you require and the desired level of accuracy.
