Question

You synthesized a brand new liquid compound in your organic chemistry lab and determined it's density to be 1.78g/ml. How could you use this knowledge of your new compound in the future, particularly if you wanted to add .100g of it to your next reaction without using a balance?

Answer 1

Answer: Measure the volume of that compound which 56.17 ml for 100 grams of that compound.

Step-by-step explanation:

Density is defined as mass present in unit volume of the substance .

`Density=(Mass)/(Volume)`

Density of the new liquid compound = 1.78 g/ml

In future if we wanted to to 100 gram of this compound without measuring its mass on the balance. What we can do is we can calculate its volume which we will require in a reaction with the help of density.

`Density=\frac{\text{Mass of the compound needed}}{\text{Volume of the compound}}=1.78 g/ml=(100 g)/(Volume)`

`Volume=(100 g)/(1.78 g/ml)=56.17 ml`

So, instead of measuring the mass of the compound we can directly measure the volume of that compound which 56.17 ml for 100 grams of that compound.
