Answer:N=1151724138 atoms
Explanation:The atomic radius of molybdenum atom is 145 picometers so lining up molybdenum atoms is like lining up the beads of radius 145 picometers
so one bead would cover the length of 145*2=290 picometers
hence the atom's diameter =D=290 picometers
D=290 *10^(-12)
also
Distance span= 33.4 cm
Distance span= 0.334m
As the Distance span adds up with no of atoms the resulting formula is
Distance span by atoms= No of atoms * atom's diameter
so
Answer:
Sugar, sodium chloride, and hydrophilic proteins are all substances that dissolve in water. Oils, fats, and certain organic solvents do not dissolve in water because they are hydrophobic.
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
I don't see any options so there i hope it helps .
