Two solutions (one yellow and one green) have the same density. The yellow solution has mass of 357g and volume of 211 cm3. Find the volume of the green liquid having 1.45 kg mass.

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.
