A 50.0mL sample of ethylene glycol had a mass of 55.505g. Find the density of ethylene glycol.
To find the density of ethylene glycol, we need to use the formula:
Density = Mass / Volume
In this case, the mass of the ethylene glycol is given as 55.505 g and the volume is given as 50.0 mL.
Before we can calculate the density, we need to ensure that the units for mass and volume are compatible. In this case, since the mass is given in grams and the volume is given in milliliters, we need to convert the volume from milliliters to grams.
The conversion factor we can use is 1 mL = 1 g, which means that the density of ethylene glycol is the same as its specific gravity. Therefore, we can directly convert from mL to g.
Now, let's calculate the density:
Density = 55.505 g / 50.0 mL
Density = 1.11 g/mL
Therefore, the density of ethylene glycol is 1.11 g/mL.
