Determine the mass of the rock using correct significant digits. the density of the rock is 3.678 g/ml

Rocks come in different sizes, shapes, and compositions. The igneous, sedimentary, and metamorphic rocks associated with each other as the distinct stages in the rock cycle. In order to find the density of the rock, there is a need to measure the mass of the rock in grams and volume in cubic centimeters.  

The density of the rock equals the mass of the rock divided by the volume of the rock. Density = mass / volume

However, from the given data, we are lacking what the volume is.  

you dont brother god luck

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
