Question

The density of glycerol is 1.26 g/mL. The density of mercury is 13.6 g/mL. How many grams of glycerol will occupy the same volume as 14.4 grams of mercury?

Answer 1

We have 1.34 grams of glycerol

Step-by-step explanation:

Step 1: Data given

Density glycerol = 1.26 g/mL

Density mercury = 13.6 g/mL

Mass of mercury = 14.4 grams

Volume of glycerol = volume mercury

Step 2: Calculate volume of mercury

Volume mercury = mass / density

Volume mercury = 14.4 grams / 13.6 g/mL

Volume mercury = 1.06 mL

Step 3: Calculate mass of glycerole

Volumer mercury = volume glycerole

Volume glycerol = mass /density

mass glycerol = volume glycerol * density

mass glycerol = 1.06 mL * 1.26 g/mL

Mass glycerol = 1.34 grams

We have 1.34 grams of glycerol

Answer 2

mass glycerol = 1.334 g

Step-by-step explanation:

∴ δ glycerol = 1.26 g/mL

∴ δ mercury = 13.6 g/mL

∴ mass mercury = 14.4 g

⇒ Volume mercury = (14.4 g)×(mL/13.6 g) = 1.059 mL

mass glycerol will occupy V = 1.059 mL:

⇒ ( Xg glycerol)( mL/1.26 g glycerol) = 1.059 mL

⇒ Xg glycerol = ( 1.059 mL )( 1.26 g/mL ) = 1.334 g glycerol
