The questions you can answer are
1) what is the mass of one mole of raindrops?, and
2) How many moles of raindrops are in the pacific ocean
Solutions:
1) what is the mass of one mole of raindrops?
mass = number of rain drops * mass of on rain drop
The number of rain drops in one mole of rain drops is 6.02 * 10^23
So, the mass of one mole of rain drops is
6.02 * 10 ^ 23 rain drops * 50. mg * (1 kg / 1,000,000 mg) = 3.01 * 10^ 19 kg
The correct number of significant digits is 2, because 50. mg has two signficant digits, so the answer must be shown as 3.0 * 10^ 19 kg.
2) How many moles of raindrops are in the pacific ocean
Use the proportion 1 mol / 3.0 * 10^19 kg = x mol / 7.08 * 10^20 kg
And you solve for x:
x = (7.08 * 10^20 kg) * 1 mol / (3.0 * 10^19 kg) = 2.36 * 10 = 23.6 moles
Which rounded to two significant digits is 24 moles of rain drops.
There are 1 .5 million atoms in moles

Answer # Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.
Answer:
-2,802.960 kJ
Explanation:
The dimensional equation of the given quantities is presented as follows;
(6 mol) × (-393.5 kJ/mol) + (6 mol) × (-285.83 kJ/mol) - (1 mol) × (-1,273.02 kJ/mol) = ? kJ
The equation, can be written as follows;
We note that 
, therefore, the above equation becomes;
Answer:
every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change by force impressed on it
Explanation:
Before release: object in a state of rest, airspeed is at zero, weight but no drag
When object is released: Object accelerates - the airspeed increases
