Question

find the density of the stone​

Answer 1

Answer:

Subtract the initial, water-only, volume from the final, water and rock, volume to find the volume of the rock. So, if the initial water volume is 30 milliliters and the final water plus rock volume is 45 milliliters, the volume of the rock alone is 45-30=15 milliliters, or 15 cubic centimeters.

Answer 2

• Placing the rock sample in a container with defined volume indications, such as a measuring cup, is necessary to determine volume by water displacement.
• Pour enough water into the cup to thoroughly immerse the rock before adding it.
• Calculate how much water there is in a container. Make sure there are no bubbles on the rock before adding it.
• Calculate the amount of water produced as a consequence of this process.
• To calculate the volume of the rock, subtract the starting water-only volume from the final water-and-rock volume.
• If the original water volume is 30 mL and the final water + rock volume is 45 mL, the volume of the rock alone is 45-30=15 mL, or 15 cubic centimeters.
