Boiling Point 356.58° C
Density 13.456 grams per cubic centimeter
Normal Phase Liquid
Family Transitions Metals
Period Number 6
Subtracting the mass of (flask+water) from the empty flask gives:
95.023 g - 85.135 g = 9.888 grams of water
Dividing this by the given volume of 10.00 mL water gives:
9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water
Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.
Answer:
The body with 2.7
has a larger volume
Explanation:
There is a missespelling in the question. The units of density cannot be g, they usually are 
In order to answer this question, we need to use the formula of the density of a body:

For body A:
Mass (M) = 5.0 g
Density (D) = 2.7 
2.7
= 5g * 1/V
V1 = 5g / (2.7
)
V1 = 1.85 
For Body B:
Mass (M) = 5.0 g
Density (D) = 8.4 
8.4
= 5g * 1/V
V2 = 5g / (8.4
)
V2 = 0.59 
So V1 is bigger than V2
Answer:
d
They do not depend on the amount of substance you have.
Answer: Stimulus
Explanation: The definition of Stimulus is "a thing or event that evokes a specific functional reaction in an organ or tissue," according to the Oxford Dictionary. So the book dropping and causing a noise is an example of a stimulus.
