Investigate: Note the empty jars on the shelf that can be filled by using the slider. Set the amount to 2.000 moles of carbon (mol C), then press Start. Each jar holds exactly one mole of carbon. Your goal is to determine the mass in grams of two moles of carbon. Before you can find the mass, what do you need to know?

Turn on Show molar mass. What is the molar mass of carbon?

What do you think the mass of 2.000 moles of carbon will be?

Drag the jars to the balance. What is the mass of 2.000 moles of C?
