A good reference to use when estimating the mass of a small object is _____. It has a mass of about_________.

Thank you!

An estimate of the mass of a new, unsharpened pencil is about 7 grams. The actual mass may vary depending on the brand and model of the pencil, but on average, a standard unsharpened pencil weighs around 7 grams.

As for the reference to use when estimating the mass of a small object, a good tool to consider is a common household scale. These scales are typically precise enough to measure small objects accurately. To determine the mass of the reference object, you can place it on the scale and read the displayed amount in grams. It's important to note that the exact value of the reference object may depend on the specific scale being used.

Therefore, I cannot provide a definitive answer for the mass of the reference object, but you can easily obtain it by using a common household scale.
