Answer:
Explanation:
1. Calculate the molar mass of Na₂SO₄
The molar mass of Na₂SO₄ is 142 g/mol.
2. Calculate the moles of Na₂SO₄
3. Calculate the mass of Na₂SO₄
In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. In this experiment, aphenolphthalein<span> color indicator will be </span>used<span>.
</span>Phenolphthalein<span> is colorless in acidic solutions and pink in basic solutions.

Answer:
35g/l
Explanation:
Salinity is practically the saltiness of the water, in basic terms. It's basically the amount of salt dissolved in water. Ocean water has a salinity of around 35g/l (that's about 3.5% of which is dissolved salt in water!). However, Atlantic Ocean (the ocean with the saltiest water), can range up to 37g/l.

Answer:
Mass = 19.78 g
Explanation:
Given data:
Mass of NO produced = ?
Mass of NO₂ reacted = 60.0 g
Solution:
Chemical equation:
3NO₂(g) + H₂O(l) → 2HNO₃(g) + NO(g)
Number of moles of NO₂:
Number of moles = mass/molar mass
Number of moles = 60.0 g/ 46 g/mol
Number of moles = 1.3 mol
Now we will compare the moles of NO₂ with NO.
NO₂ : NO
3 : 1
1.3 : 1/3×1.3 = 0.43 mol
Mass of NO:
Mass = number of moles × molar mass
Mass = 0.43 mol × 46 g/mol
Mass = 19.78 g
