Determine all equilibrium solutions (i. e., constant solutions that other solutions approach as t→[infinity]t→[infinity]) of the following nonhomogeneous linear system: y⃗ ′(t)=[−333−3]y⃗ (t)+[1−1]. y→′(t)=[−333−3]y→(t)+[1−1]. As t→[infinity]t→[infinity], the equilibrium solution has the form y⃗ =y→= ⎡⎣⎢⎢[ ⎤⎦⎥⎥] + c+ c ⎡⎣⎢⎢[ ⎤⎦⎥⎥]

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

the answer is na (sodium)
