Multi-step problems
A problem that asked you to convert molecules to grams could require two steps
1. convert the molecules to moles
2. convert to moles to grams
You learned how to convert molecules to moles in part A. In part C you converted grams to moles, but the same conversion factor inverted would convert moles to grams. You can use these parts to help perform each s
You could also do this in one step by using the conversion factors employed in part A and C to create a new conversion factor that completes the conversion in one step.

Part D
control
Sodium hydroxide, NaOH, is a strong base that is used in industrial synthesis and processes such as making paper.
What is the mass of 2.60×1022 formula units of NaOH (Molar mass = 40.0 g/mol)?
Express the mass in grams to three significant figures.
