Find the specific gravity of Ethyl Alcohol if 70.0 g occupies 850 mL.

Answer 1

The formula for specific gravity is:

specific gravity = density of the substance/density of water at 4°C

First, we need to calculate the density of Ethyl Alcohol. We know that 70.0 g of Ethyl Alcohol occupies 850 mL, so we can use the following formula:

density = mass/volume

density = 70.0 g / 850 mL

density = 0.08235 g/mL

Next, we need to find the density of water at 4°C. This is a standard value of 1 g/mL.

Now we can use the formula for specific gravity:

specific gravity = density of the substance/density of water at 4°C

specific gravity = 0.08235 g/mL / 1 g/mL

specific gravity = 0.08235

Therefore, the specific gravity of Ethyl Alcohol is 0.08235.
