A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4
Harman [31]
Na₃PO₄ -----> 3Na(+) + PO₄(3-)
y-y.......................3y...........y

3y = 1.2
y = 0,4M

Na₃PO₄ -----> 3Na(+) + PO₄(3-)
0,4-0,4..............1,2..........0,4
0.........................1,2..........0,4

C = n/V
n = C×V
n = 0,4×0,65L
n = 0,26 mol Na₃PO₄

mNa₃PO₄: (23×3)+31+(16×4) = 164 g/mol

164g ----- 1 mol
Xg -------- 0,26 mol
X = 164×0,26
X = 42,64g Na₂SO₄

What is true of the total mass of reactants compared to the total mass of products
kaheart [24]

Answer:

The total mass of reactants equals the total mass of products  

Step-by-step explanation:

The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:

Reactants ⟶ products

Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
