We have an aqueous solution that contains 35% (by mass) of a hypothetical solute Z. The formula weight of the solute Z is 118 g/

Allisa [31]

Answer:

4.15 M

Explanation:

In order to find the molarity of a stock solution of Z, we use the formula;

Co = 10pd/M

where;

p = percentage by mass of Z

d = density of Z

M= molar mass of Z

Substituting values;

Co= 10 * 35 * 1.4/118

C0= 4.15 M

3.40mol P2O5 to grams P2O5

Inessa05 [86]

<h3>Answer:</h3>

482.596 grams

<h3>Explanation:</h3>

The relationship between moles, molar mass and mass of a compound is given by;

$Moles =\frac{mass}{molar mass}$

In this case;

The compound in question is P₂O₅

Molar mass of P₂O₅ = 141.94 g/mol

Rearranging the formula;

Mass = Moles × molar mass

Therefore;

Mass of P₂O₅ = 3.4 mol × 141.94 g/mol

= 482.596 grams

Therefore, mass of P₂O₅ is 482.596 grams
