a sample of sucrose that weighs 9.35 g is placed in a 15ml flask and the remaining volume of the flask is filled with benzene. the density of benzene is 0.879g/cm3. the sucrose and benzene together weigh 17.33g. what is the density of the sucrose?

The density of sucrose is 1.58 g / cm³

Calculation

Step 1 : calculate the volume of benzene

volume = mass/density

mass of benzene = total mass - mass of sucrose

=17.33 g - 9.35 g = 7.98 g

volume = 7.98 / 0.879 = 9.08 cm³

Step 2: calculate the volume of sucrose

volume of sucrose = Total volume - volume of benzene

Total volume = 15 ml = 15 cm³

volume of sucrose is therefore = 15 cm³ - 9.08 cm³=5.92 cm³

Step 4: calculate the density of sucrose

density = mass/volume

= 9.35 g / 5.92 cm³ = 1.58 g/cm³
