How many liters of a 3.86 m k2so4 solution are needed to provide 72.9 g of k2so4 (molar mass 174.01 g/mol)? recall that m is equivalent to mol/l.

0.109 L of will be needed

Explanation:

Given the molarity of    is 3.86M

Molar mass of   = 174.01 g/mol

Weight/Mass of solute  is given as 72.9 g

Moles of  based on the values given

=

By definition,

Molarity =

And thus, volume =

Substituting the values in the above formula,

Volume =  

Therefore, 0.109 L of   will be needed

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.
