An object has a mass of 20 g and volume of 10 cm3. Enter the numerical value for the density of the object in units of g/cm3.

2g/cm3 is ur answer, hope this helps :)

Explanation: when solving for the density, the formula would be d=m(mass)/v(volume). therefore you need to take the volume and divide that into the mass to get density. in this case your mass is 20 and volume is 10. so you divide those two and you will get your answer of 2g/cm3.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
