Step 1: Define

23.9 g Ti (Titanium)

Step 2: Identify Conversions

[PT] Molar Mass of Ti - 47.88 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

0.499165 mol Ti ≈ 0.499 mol Ti

Explanation:

To convert from grams to moles, we must use the molar mass, which can be found on the Periodic Table.

Use this number as a fraction.

Multiply by the given number of grams: 23.9

Flip the fraction so the grams of titanium cancel out.

Divide.

The original measurement had 3 significant figures, so our answer must have the same. For the number we calculated, that is is the thousandth place. The 2 in the ten thousandth place tells us to keep the 9.

There are 0.499 moles of titanium in 23.9 grams.
