What would happen if you dropped the object into the beaker while using the Archimedes' Principle method? The measurement displayed on the digital scale would be incorrect.

To help you get a feel for metric measurements, you need to know the relative magnitude of a few basic measurements. For example: 1 mm = thickness of a dime; 2.5 grams = weight of a penny; 20°C = normal room temperature.

What weighs approximately 1 g? A small paperclip.

What is approximately 1 cm long, wide or thick? Fingertip is approx 1 cm wide.

What weighs about 100 g? 40 pennies

What weighs about 1000 g? One liter of water

While heating two different samples of water at sea level, one boils at 102 degrees C and one boils at 99.2 degrees C. Calculate the percent error for each sample from the theoretical 100.0 degrees C. First sample boils at 102 degrees C, so the percent error is 2%. The second sample boils at 99.2 degrees C, so the percent error is -0.8%.

An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide. If the mass is 21.3g, what is this substance's density? Density is equal to 1.20.

A sample of gold (Au) has a mass of 26.15 g. Given that the theoretical density is 19.30 g/mL, what is the volume of the gold sample? In order to work this problem, the equation density equals mass divided by volume must first be solved for volume. The volume of the gold sample is equal to 1.36 mL.
