At 20 °C, chloroform (CHCl3) has a density of 1.489 g/mL. What is the mass of 7.52 mL of chloroform at 20°C?
To calculate the mass of chloroform (CHCl3) at 20°C, we need to use the density of the substance.
The density of chloroform is given as 1.489 g/mL, which means that for every 1 mL of chloroform, it has a mass of 1.489 grams.
To find the mass of 7.52 mL of chloroform, we simply multiply the volume (in mL) by the density (in g/mL).
Mass = Volume × Density
Mass = 7.52 mL × 1.489 g/mL
Now, we can calculate the mass:
Mass = 11.1848 g
Therefore, the mass of 7.52 mL of chloroform at 20°C is approximately 11.1848 grams.
To find the mass of chloroform, we can use the formula:
Mass = Density × Volume
Given:
Density of chloroform at 20 °C = 1.489 g/mL
Volume of chloroform = 7.52 mL
Substituting the given values into the formula:
Mass = 1.489 g/mL × 7.52 mL
Calculating the result:
Mass = 11.192 g
Therefore, the mass of 7.52 mL of chloroform at 20 °C is 11.192 grams.
mass = volume x density
Substitute and solve.
