If the mass of a material is 98 grams and the volume of the material is 12 cm3, what would the density of the material be?

The answer is 8.17g/cm³
Density is defined as mass per unit of volume. With that definition, you can come up with the formula:



Where:
D = density
m = mass
v = volume

Based on the problem, your given is as follows:
m=98g
v= 12cm³

All you need to do is input the data that you know into the formula and solve for what you don't know:

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
