Hey the density of the material that has the mass of 52.45 g and a volume of 13.5 cm

Density has a formula of p=m/V

p= density

m= mass

V= volume (*make sure it is a capital V*)

So plug in what we know:

m= 52.45g

V= 13.5 cm

So now plug it into the formula

p= 52.45g/13.5 cm

and solve to get:

4.03333 g/cm

The 3 is repeating so make sure to adjust for significant figures if that applies.  

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).
