If i have 6 grams of sugar and dissolve it in 74 ml of water, what is the concentration?

Given that  

Amount of sugar = 6 g

Volume of water = 74 ml or 0.074 L

Number of moles of sugar = amount in g  / molar mass

= 6 g/ 342.3 g/mol

=0.018 moles  

Therefore molarity or concentration = 0.018 mole / 0.074 L

= 0.24 M

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.

⇌(double head arrow) means reversible reaction).
