Answer:
Therefore, the density of the substance is 0.67 g/mL
Explanation:
Density=VolumeMassTo find the density of the substance, we can use the following steps:Calculate the mass of the substance per mL at the initial volume of 90 mL:Mass per mL=60 g90 mL=0.67 g/mLMass per mL=90 mL60 g=0.67 g/mLCalculate the mass of the substance at the final volume of 75 mL:Mass=Volume×DensityMass=Volume×DensityMass=75 mL×0.67 g/mL=50.25 gMass=75 mL×0.67 g/mL=50.25 gCalculate the density of the substance at the final volume of 75 mL:Density=MassVolume=50.25 g75 mL=0.67 g/mLDensity=VolumeMass=75 mL50.25 g=0.67 g/mL
