The value of x : 2
<h3>Further explanation</h3>
Semi-normal Hydrochloric acid solution = 0.5 N = 0.5 M
for titration :
M₁V₁n₁=M₂V₂n₂(1=HCl,2=Na₂CO₃)
MW Na₂CO₃.xH₂O=143
MW Na₂CO₃.xH₂O = MW Na₂CO₃+ MW xH₂O = 143
MW Na₂CO₃ = 106 g/mol
MW xH₂O = 18x
Equation :
Answer:
The answer is
<h2>0.35 g</h2>
Explanation:
The mass of a substance given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 0.253 mL
density = 1.38 g/mL
Substitute the values into the above formula and solve for the mass
We have
mass = 1.38 × 0.253 = 0.34914
We have the final answer as
<h3>0.35 g</h3>
