what is the density that has a mass of 77.0 g and a volume of 36 mL?
mass = density x volume. Plug and chug!
D=M/V so you have Mass: 77g and volume : 36 mL
=> D = 77/36 =2.1 g/mL
To calculate the density, you divide the mass by the volume. Given a mass of 77.0 g and a volume of 36 mL, the density can be calculated as:
Density = Mass / Volume
Density = 77.0 g / 36 mL
However, to ensure consistent units, it is important to convert mL to grams. Since the density of water is often referenced, which has a density of 1 g/mL, we can use this conversion factor.
1 mL = 1 g
Therefore, the density can also be calculated as:
Density = 77.0 g / 36 g
Now, let's calculate the density:
Density = 2.139 g/mL
To find the density, you need to divide the mass by the volume. The formula for density is:
Density = Mass / Volume
Given that the mass is 77.0 g and the volume is 36 mL, you can substitute these values into the formula:
Density = 77.0 g / 36 mL
However, before calculating the density, it is important to note that the units of mass and volume should be compatible. In this case, grams (g) are compatible with milliliters (mL), so no conversion is needed.
Now you can perform the calculation:
Density = 77.0 g / 36 mL
Density ≈ 2.14 g/mL
Therefore, the density of the substance is approximately 2.14 g/mL.
