It has 4 significant figures. If you see the Zero after the one decimal point you don’t count that and instead just started at 6
2. amount of sunlight
3. plant growth
4. x axis- amount of sunlight. y axis- plant growth
5. A bar graph would best represent the data the students found because they are used to compare things between different groups.
The density of the material is 2.66 g/mL and it is likely this is made of Aluminum
Explanation:
The first step to know the material of the chunk of metal is to calculate its density. The general formula for density is P (density) = . Moreover, in this case, it is known the mass is 37.28 g, but the volume is not directly provided. However, we know the water in the graduated cylinder had a volume of 20.0 mL and this increased to 34.0 mL when the chunk of metal is added, this means the volume of the metal is 14 mL (34.0 mL - 20.0 mL = 14 mL). Now let's calculate the density:
This means the density of this metal is 2.66 g/mL, which can be rounded as 2. 7 g/mL, and according to the chart, this is the density of aluminum. Therefore, this material of this chunk is aluminum.
Answer:
Hope the above picture might help you :)
