Hei has the element shown for his science experiment. How many kilograms of the material does he have?
(1,000 grams = 1 kilogram)

3.508 kg of the material

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My

Given that:

1 kilogram is 1000 grams.

A box that has three thousand, five hundred eight grams <=> 3508 grams

How many kilograms of the material does he have? we have got:

x kg - 3508g

<=> 1000x = 3508

<=>

<=> x = 3.508

So he has 3.508 kg of the material

Hope it will find you well.
