Answer:
001: 71.2 g per ML
002: Consider a block of marble that occupies 287 cm3 and has a mass of 869 g.
a. What is its density?
d=m/v=869g/287 cm3=3.03 g/cm3
b. Will it float in:
H2O(l)? Why or why not?
Nope! Density > 1.00 g/mL
Hg(l) (density=13.55 g/mL)? Why or why not?
Yep! Density < 13.55 g/mL
003:
Use the given functions to set up and simplify
0.309 cm3
g/cm3=g/cm3
0.309cm3=g/cm3

Hope this helps I tried my best
Answer:
None of carbonyl group is attached to hydrogen atoms.
Explanation:
Ketone is a group in which one carbonyl group is attached to two R ( the alkyl group) .
And the group in which two hydrogen is attached to R is called as aldehyde (formaldehyde).
And when one hydrogen and one alkyl group is attached to R. It is called as acetaldehyde from aldehyde family.

5.426 x 
molecules are there in a deep breath of air whose volume is 2. 35 L at body temperature 36 C and a pressure of 740 torr.
Explanation:
Data given:
volume V = 2.35 L
Temperature T = 36 Degrees or 273.15 + 36 = 309.15 K
pressure P = 740 torr OR 0.973 Atm
R = 0.08205 L atm / mole K
n (number of molecules of gas)= ?
The formula used will be
PV = nRT
Putting the value of given variables in above equation:
n = 
= 
= 0.0901 moles
According to Avagadro' s law that gases at equal volume, temperature and pressure contains same molecules.
number of molecules:
number of moles x avagadro number
0.0901 x 6.02 x 
= 0.54 x
= 5.426 x molecules.
Explanation:
the air particales are always moving so it also takes the smell of the chesse with it and sreads everywhere in the house.
The result of multiplying that equation is 70,700.
