A flask contains 25.0 mL of diethyl ether weighth 18.74 µg (micrograms). What is the density of the diethyl ether and grams per liter?

I'm not sure how to set this problem up correctly.

Why don't you just change mL to L and change ug to grams. Then d = m/v directly in g/L.

To determine the density of diethyl ether, you need to divide the mass of the diethyl ether by its volume.

First, convert the mass of the diethyl ether from micrograms to grams:
18.74 µg = 18.74 × 10^-6 g

Next, convert the volume of the diethyl ether from mL to L:
25.0 mL = 25.0 × 10^-3 L

Now, you can calculate the density using the formula:
Density = Mass / Volume

Density = (18.74 × 10^-6 g) / (25.0 × 10^-3 L)

Simplifying the expression, we have:
Density = 0.7496 g/L

Therefore, the density of the diethyl ether is 0.7496 g/L.

To find the density of diethyl ether, you need to use the equation:

Density = Mass/Volume

First, convert the mass of diethyl ether from micrograms (µg) to grams (g).

Given: Mass = 18.74 µg

1 µg = 10^(-6) g (conversion factor)

Therefore, Mass = 18.74 µg × 10^(-6) g/µg = 18.74 × 10^(-6) g = 0.00001874 g

Next, convert the volume of the flask from milliliters (mL) to liters (L).

Given: Volume = 25.0 mL

1 mL = 10^(-3) L (conversion factor)

Therefore, Volume = 25.0 mL × 10^(-3) L/mL = 0.025 L

Now, you can substitute the values into the density equation:

Density = Mass/Volume

Density = 0.00001874 g / 0.025 L

Density = 0.0007496 g/L

Therefore, the density of diethyl ether is approximately 0.0007496 g/L.

To find the density in grams per liter (g/L), you simply divide the mass (in grams) by the volume (in liters) as shown above.
