The density of a substance can be found using the following formula:
d= m/v
where m is the mass and v is the volume.
The mass of this substance is 49.1 grams and the volume is 24.7 milliliters.
m= 49.1 g
v= 24.7 mL
Substitute these values into the formula.
d= 49.1 g / 24.7 mL
Divide 49.1 g by 24.7 mL
d= 1.98785425 g/mL
We are asked to round to two decimal places, or the hundredth place. The 8 in the thousandth place tells us to round the 8 to a 9 in the hundredth place.
d ≈ 1.99 g/mL
The density of the this substance is approximately 1.99 grams per milliliter.
It is important for scientists to review the work of other scientists, so they can be sure there are no mistakes or lack of judgement. They repeat to compare results to make hypotheses.
<em>The process of photosynthesis</em> is used to help make food for plants. The inputs are sunlight, water (H2O), and carbon dioxide (CO2). Then the outputs are glucose (C6H12O6) which is food, and oxygen (O2) is released.
