How many cups are in 1680 grams of sugar?

Steps:

1. Convert grams to kilograms:

1680 grams / 1000 = 1.68 kilograms

2. Use density to calculate the volume in liters:

Density of sugar = 0.95 kilograms per liter (approximate value)

Volume (liters) = mass (kilograms) / density (kilograms per liter)

Volume (liters) = 1.68 / 0.95 = 1.77 liters

3. Convert liters to cups:

1 liter = 4 cups

Volume (cups) = Volume (liters) x Conversion factor (cups/liter)

Volume (cups) = 1.77 x 4 = 7.08 cups

Conclusion:

1680 grams of sugar is equivalent to approximately 7.08 cups of sugar.
