Answer:

The concentration of Mg3P2 solution = 0.24mol/L

Explanation:

Mass = 81.1g

Volume = 2.5L

Concentration (C) of a solution = \frac{Moles (n)}{Volume (V)}

but moles = \frac{mass}{Molar mass}       and      Molar mass of Mg3P2 = 134.88g/mol

Moles = \frac{81.1g}{134.88g/mol}

          = 0.60mol

hence the concentration can be calculated by;

C =  \frac{0.60mol}{2.5L} \\

  = 0.24mol/L or 0.24M

Elza [17]

Answer:

12.10 mol / 1 L

Explanation:

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity ( unit = mol / L or M )

V = volume of solution in liter ( unit = L ),  

n = moles of solute ( unit = mol ),  

Moles is denoted by given mass divided by the molecular mass ,  

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .  

From the question ,

The data given is as follows -

w = 439 g

As , we known for HCl ,

m = 36.46 g/mol

V = 1 L

From the above data ,

Moles are given as -

n = w / m

n = 439 / 36.26 = 12.10 mol ,

Now , the molarity is given as ,

M = n / V

M = 12.10 mol / 1 L

M = 12.10 mol /L
