Answer:

22.35 g of  (NH₄)₃PO₄ will be produced by 7.5 g of ammonia.

Explanation:

H₃PO₄ + 3NH₃  → (NH₄)₃PO₄

H₃PO₄: 98 g/mol

NH₃: 17 g/mol

(NH₄)₃PO₄: 149 g/mol

17 g NH₃ _________ 1 mol

7.5 g NH₃ __________ x

  x = 0.44 mol NH₃

3 mol NH₃ __________ 1 mol (NH₄)₃PO₄

0.44 mol NH₃ _________           y

     y = 0.15 mol (NH₄)₃PO₄

1 mol (NH₄)₃PO₄ ____________ 149 g

0.15 mol (NH₄)₃PO₄ __________    z

          z = 22.35 g (NH₄)₃PO₄

What is the mass in grams of 4.85 x 1022 al atoms?
aliya0001 [1]

Based on the calculations, the mass of Aluminum in 4.85 × 10²² atoms is equal to 2.1762 grams.

<h3>How to calculate the mass of Aluminum?</h3>

In order to determine the mass of Aluminum, we would calculate the number of atoms in 1 mole of an Aluminum atom in accordance with Avogadro's constant.

1 mole of Aluminum atom = 6.02 × 10²³ molecules

X moles of Aluminum atom = 4.85 × 10²² molecules

Cross-multiplying, we have:

X = 4.85 × 10²²/6.02 × 10²³

X = 0.0806 moles.

Mass = Molar mass × Number of moles

Mass = 27 × 0.0806

Mass = 2.1762 grams.
