Sam is making an aquaponics garden. He needs 2.3 dkg of granite. He has 460 g. How much more does he need? Explain your answer with your work.

Explanation:

He needs 2.3 dkg

dkg is a unit of mass and represents dekagrams.

The relationship between dkg and g is given as;

1 dkg = 10g

This means he needs 2.3 * 10 = 23 g of graphite.

Since he already has 460g of graphite, he doesn't need any additional graphite.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
