<h3>
Answer:</h3>
266.325 g
<h3>
Explanation:</h3>
We are given the balanced equation;
2NaOH + H₂SO₄ → H₂O + Na₂SO₄
We are required to determine the mass of Na₂SO₄ that will be formed.
<h3>Step 1: Determine the number of moles of NaOH</h3>
Moles = Mass ÷ molar mass
Molar mass of NaOH is 40.0 g/mol
Therefore;
Moles of NaOH = 150 g ÷ 40 g/mol
= 3.75 moles
<h3>Step 2: Determine the number of moles of sodium sulfate formed</h3>
- From the equation 2 moles of NaOH reacts with sulfuric acid to form 1 mole of sodium sulfate.
- Therefore; mole ratio of NaOH : Na₂SO₄ is 2 : 1
Thus, moles of Na₂SO₄ = Moles of NaOH ÷ 2
= 3.75 moles ÷ 2
= 1.875 moles
<h3>Step 3: Determine the mass of Na₂SO₄ produced.</h3>
we know that;
Mass = Moles × Molar mass
Molar mass of Na₂SO₄ is 142.04 g/mol
Therefore;
Mass of Na₂SO₄ = 1.875 moles × 142.04 g/mol
= 266.325 g
Thus, the mass of sodium sulfate formed 266.325 g

6.7 mass because 1 atom equals 6.3 but if u add 4 it would be 6.7
A Wedge is made by placing two inclined planes back to back.
A Screw is made by wrapping an inclined plane around a cylinder.
<u>Explanation:</u>
- A wedge is an uncomplicated machine that consists of two sloping planes, providing it a thin end and thick end.
- A wedge is used to separate or split apart objects.
- Force is employed to the thick end of the wedge, and in turn, applies force to the object along both of its sloping sides.
- A screw is a simplistic machine that consists of an inclined plane wrapped around a cylinder or cone.
- The absolute mechanical benefit of wedges and screws is invariably higher than 1.
