What is the current in amperes if 1200 na+ ions flow across a cell membrane in 3.5 μs ? the charge on the sodium is the same as on an electron, but positive?

Explanation:

It is given that,

Number of Na⁺ ion, n = 1200 C

So, total charge,

Time taken to flow the charges, t = 3.5 μs = 3.5 × 10⁻⁶ s

Electric current is defined as the ratio of electric charge per unit time.

So, the current flowing in the circuit is

where is the following

explanation:

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.
