Answer :
Final answer:
The mass of Na3PO4 in a 35.9 mL solution is found by multiplying the density by the volume. The solution thus contains approximately 39.49 grams of Na3PO4.
Therefore correct option is 1.
Explanation:
The subject of this question is Chemistry and it's a problem related to molarity and density. To solve this problem, we need to multiply the volume of the solution by its density to find the mass. The formula is mass = density * volume. So, 1.10g/mL * 35.9mL = 39.49g. Therefore, there are approximately 39.49 grams of Na3PO4 in a 35.9 mL solution of Na3PO4.
