Question

Nobody was answering my question in "Chemistry" So I'll have to post it here:

A flask that weighs 345.8 g is filled with 225 ml of carbon tetrachloride. The weight of the flask and carbon tetrachloride is found to be 703.55g. Calculate the density in g/ml and g/L.

Answer 1

1.59 g/mL

Explanation:

To calculate the density of the carbon tetrachloride, we need to divide the mass of the carbon tetrachloride by its volume.

The mass of the carbon tetrachloride can be found by subtracting the mass of the empty flask from the mass of the flask and carbon tetrachloride:

mass of carbon tetrachloride = (mass of flask and carbon tetrachloride) - (mass of empty flask)

mass of carbon tetrachloride = 703.55 g - 345.8 g

mass of carbon tetrachloride = 357.75 g

The volume of the carbon tetrachloride is given as 225 mL.

Now we can calculate the density of the carbon tetrachloride:

density = mass / volume

density = 357.75 g / 225 mL

To convert this density to g/L, we need to multiply by the conversion factor 1000 mL/L:

density = (357.75 g / 225 mL) * (1000 mL/L)

density = 1,590 g/L

Therefore, the density of the carbon tetrachloride is 1.59 g/mL or 1,590 g/L.
