Lithium is a soft, gray; solid that has the lowest density of any metal. If a rectangular slab of lithium weighs 1.49x10^3 mg and has a volume of 2.76 cm^3, what is the density of lithium in g/cm^3? Please and thank you!

mass = volume x density.

You know mass from the problem (you should convert to grams) and you know volume. Solve for density.

To find the density of lithium, you need to divide its mass by its volume.

1. Convert the mass from milligrams (mg) to grams (g):
1.49 x 10^3 mg = 1.49 x 10^3 g

2. Divide the mass by the volume to find the density:
Density = Mass / Volume
Density = 1.49 x 10^3 g / 2.76 cm^3

3. Now, calculate the density by using the given mass and volume:
Density = 539.13 g/cm^3

So, the density of lithium is 539.13 g/cm^3.

To find the density of lithium in g/cm^3, we need to use the formula:

Density = Mass / Volume

First, we need to convert the mass from milligrams (mg) to grams (g). We can use the conversion factor: 1 g = 1000 mg.

Given that the mass of the rectangular slab of lithium is 1.49x10^3 mg, we can convert it to grams as follows:

1.49x10^3 mg * (1 g / 1000 mg) = 1.49 g

Next, we can substitute the values into the density formula:

Density = Mass / Volume = 1.49 g / 2.76 cm^3

Calculating the division, we get:

Density = 0.539 g/cm^3

Therefore, the density of lithium is 0.539 g/cm^3.
