Well, you could get the mass as
ad then
, where
is the sea level weight,
the sea level accel.,
the accel. above while
the weight above.
Molality= moles NaCl/ Kg H2O
250 g (1 Kg/ 1000 grams)= 0.250 Kg
Molality= 0.611 moles/ 0.250 Kg= 2.44 molal
Answer:
The structures are attached in file.
Hydrogen bonding and intermolecular forces is the reason for ranks allotted.
Explanation:
In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.
In order of decreasing affinity to water molecules:
This is due to the fact that the 
will accept protons more readily than the bicarbonate ion, 
. Carbonic acid, 
will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.
Answer:The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.
Answer:
the mass of a planet doesn't matter, considering many
planets are made up of gas, and how in different situations,
atmospheres can be destroyed (The Sun burnt off Mercury's
Atmosphere). However, in some cases, the planet can be in a good
situation on the galaxic map, and have great conditions for an
atmosphere, such as Earth. In which case, the mass of an object can
attract a smaller object, causing gravity. Therefore, the bigger
the mass of a planet when in right and specific conditions, the
more atmosphere it can attract, if there is any floating by the
planet.
If it is bigger it will have more gravitational influence and
therefore gather more gases.
Explanation:
hope this helped!
