Answer:
crushes the ice to compaction and satasfation
For many (but not all) problems, you can simply round the atomic weights and the molar mass to the nearest 0.1 g/mole. HOWEVER, make sure that you use at least as many significant figures in your molar mass as the measurement with the fewest significant figures. In other words, never let your molar mass be the measured value that determines how many signficant figures to use in your answer!
Answer:
Gradual refinement
Explanation:
Gradual refinement is the process whereby the System Development Life Cycle goes through a series of development stages, each stage/phase refining the previous one.
Answer:
In chemistry the substance is usually measured using molecular mass and molar mass. They are very important concepts in chemistry. Expression of molar mass is grams per mole.
...
Molar mass:
Difference between Molar mass and Molecular mass
Measurement given to compounds, atoms or molecules Determined only in molecules

242 mg of cholesterol is present in 100 mL of blood. If the total blood present in a body is 5.2 L The total body cholesterol can be calculated as follows:
First calculate concentration as follows:
C=\frac{m}{V}=\frac{242 mg}{100 mL}=\frac{242 g}{100 L}=2.42 g/L
Now, total volume is 5.2 L thus, mass will be calculated as follows:
m=C×V=2.42 g/L×5.2 L=12.584 g
Thus, the grams of blood cholesterol in human body will be 12.584 g.
