Acetone, a common solvent has a density 0.79g/cm^3 at 20C. What is the volume of 85.1g of acetone at 20C? What is the mass of 125ml of acetone at 20C? Show your calculations.
Oh, the magical world of chemistry! Let's dive in and solve these acetone conundrums, shall we?
First, to find the volume of 85.1g of acetone at 20C, we can use the formula:
Volume = Mass / Density
Plugging in the values:
Volume = 85.1g / 0.79g/cm^3
Calculating that out, we get:
Volume = 107.595 cm^3
So, the volume of 85.1g of acetone at 20C is approximately 107.595 cm^3.
Now, onto the second question: the mass of 125ml of acetone at 20C.
To determine this, we need to know the mL to g conversion since the density is given in g/cm^3. However, you haven't specified the mL to g conversion for acetone.
But fret not! As a clown bot, I'm here to entertain and solve puzzles. So, let's say that the density of acetone is 0.79 g/cm^3, which means that 1 mL of acetone weighs 0.79 g.
Using this conversion, we can calculate the mass by multiplying:
Mass = Volume x Density
Mass = 125ml x 0.79g/ml
Calculating that out, we get:
Mass = 98.75g
Therefore, the mass of 125ml of acetone at 20C, using the assumed conversion of 0.79 g/mL, is approximately 98.75g.
Remember, these calculations are based on the given density and conversion assumption. Double-check your sources for accurate values.
To find the volume of acetone, given its density and mass, we can use the formula:
Volume = Mass / Density
First, let's calculate the volume of 85.1g of acetone:
Density of acetone = 0.79g/cm^3
Mass of acetone = 85.1g
Volume = Mass / Density
Volume = 85.1g / 0.79g/cm^3
To proceed with the calculation, we need to make sure that the units are consistent. Since the density is given in grams per cubic centimeter (g/cm^3), we need to convert the mass from grams to cubic centimeters.
To convert grams to cubic centimeters, we need to know the volume occupied by 1 gram of acetone. This can be found by taking the reciprocal of the density.
Volume of 1g of acetone = 1g / 0.79g/cm^3
Volume of 1g of acetone = 1.27 cm^3
Now we can find the volume of 85.1g of acetone:
Volume = Mass / Density
Volume = 85.1g * (1.27 cm^3/g)
Volume = 107.777 cm^3
Therefore, the volume of 85.1g of acetone at 20°C is 107.777 cm^3.
Next, let's calculate the mass of 125ml of acetone at 20°C.
Given:
Density of acetone = 0.79 g/cm^3
Volume of acetone = 125 ml
To find the mass, we can use the formula:
Mass = Volume * Density
First, let's convert the volume from milliliters (ml) to cubic centimeters (cm^3) since the density is in g/cm^3.
1 ml = 1 cm^3
Now we can calculate the mass:
Mass = Volume * Density
Mass = 125 cm^3 * 0.79 g/cm^3
Mass = 98.75 g
Therefore, the mass of 125 ml of acetone at 20°C is 98.75 g.
In summary:
- The volume of 85.1g of acetone at 20°C is 107.777 cm^3.
- The mass of 125 ml of acetone at 20°C is 98.75 g.
volume is 107.72ml, mass is 85.098 g
mass = volume x density or
volume = mass/density
mass = 85.1g
density = 0.79 g/cc
