Answer:

4 grams

Step-by-step explanation:

Write and solve an equation of ratios:

 x         2/3 l

------- = ----------

3 gr      1/2 l l

Cross-multiplying, we get (1/2) x liter  = 2 gr-liter.

Dividing both sides by 1/2 liter, we get:

 

      2 gr-liter               2                  

x = ------------------ = ------------ grams = 4 grams

       1/2 liter              1/2                      

There are 4 grams of sodium in 2/3 of a liter of soda.
