Question

If the concentration of sodium ion in this average individual is 0.131 M, what is the mass of sodium ion circulating in 5.0L of blood?

Answer 1

Use the formula \[c=\frac{n}{v}\]

Answer 2

\[Also\quad convert\quad 5L\quad to\quad dm^-3\]

Answer 3

1dm^-3 = 1L

Answer 4

your saying \[\frac{ .131M }{ 5L }\]

Answer 5

From the formula you can find the no. of moles of sodium. After that find the relative atomic mass of sodium and use the \[n=\frac{m}{M}\] formula to get the mass

Answer 6

\[cv=n\]\[.131mol dm^-3*5dm^-3=n\]

Answer 7

thank you I have to figure out how to put this into my calculator

Answer 8

Ok take your time :)

Answer 9

ok so i got\[2.24*10^{02}\] is that correct?
