The answer:  1533 g {"grams"} ;  or even "1530 g" or "1500 g" ; would be an acceptable estimate.
_______________________________________________________
Note:  We are asked to:  "Estimate the weight of 6 (six) apples."

Given: (from the table—within the image attached):  
_______________________________________________________
"2 apples weigh "511 g" ; 


"then "6 apples" would weigh about 3 times that weight;  since: 

  "2 apples;  multiplied by "3" , is "6 apples" .

so:  "511 g * 3 ≈  500 g * 3 = 1500 g ". 

or:  
"511 g * 3 ≈ 510 g * 3  = (500 g * 3)  + (10 g * 3) = (1500 + 30) g = 1530 g

or:   

"511 g * 3 ≈ 511 g * 3  = (500 g * 3)  + (11 g * 3) = (1500 + 33) g = 1533 g.
______________________________________________________
Note:  The table shows that the given numbers of apples, along with their respective weights, are not [evenly and equally] proportional —reflecting the fact that there is variation among weight in apples across the board.

The weight of 6 apples from the given values is; 1533 g

Algebra Word Problems

From the given table, we see that;

Weight of 2 apples = 511 g

Weight of 5 apples = 1200 g

Weight of 8 apples = 2016 g

Thus;

If 2 apples = 511 g, then we know that 3 of such means 6 apples.

Thus;

Weight of 6 apples = 3 * 511

Weight of 6 apples = 1533 g
