Calculate the mass of 0.250 L of ethyl acetate , if the density of ethyl acetate is 0.90g / ml .
mass = volume x density.
Substitute and solve.
Given:
Volume of EtOAc = 0.250L = 250ml
Density of (EtOAc) = (0.90g/ml)
mass EtOAc = (0.90g/ml)(250 ml)= 225g.

To calculate the mass of ethyl acetate, we need to know the volume and density of the substance. In this case, we are given the volume of ethyl acetate as 0.250 L and the density as 0.90 g/mL.
To begin, we need to convert the given volume from liters to milliliters, as density is typically given in g/mL. There are 1000 milliliters (mL) in 1 liter, so we can convert 0.250 L to mL:
0.250 L * 1000 mL/L = 250 mL
Next, we can use the formula for calculating mass, which is:
Mass = Density * Volume
Given that the density is 0.90 g/mL and the volume is 250 mL, we can substitute these values into the formula:
Mass = 0.90 g/mL * 250 mL
Now, we multiply the density by the volume:
Mass = 225 g
Therefore, the mass of 0.250 L of ethyl acetate is 225 grams.
