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.

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

heat or electricity in the atmosphere- c.
