# How dense is the metal block?

To calculate the density of the metal block, we first need to convert the mass from milligrams to grams. This can be done by dividing the mass by 1000, since 1 gram is equal to 1000 milligrams.

**Mass of the block in grams:**

765mg = 765 x 10⁻³ g = 0.765g

Now, we can calculate the density using the formula:

**Density = mass/volume**

**Density = 0.765g / 0.035mL**

**Density = 21.86g/mL**

Therefore, the density of the metal block is 21.86g/mL. This means that for every milliliter of the metal block, it has a mass of 21.86 grams.
