JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry

एक व्यवसायिक ऊुप से बेचे जाने वाला सान्द्र \(HCl\) का द्रव्यमान प्रतिशत \(35 \%\) है। यदि इस अम्ल का घनत्व \(1.46\,g / mL\) है, तो इस विलयन की मोलरता \(.........M\) होगी:- (परमाणु भार: \(Cl =35.5\,amu , H =1\,amu\) )

  1. A \(10.2\)
  2. B \(12.5\)
  3. C \(14.0\)
  4. D \(18.2\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(14.0\)

Step-by-step Solution

Detailed explanation

Let total volume \(=1000 \,mL =1 \,L\) total mass of solution \(=1460 \,g\) mass of \(HCl =\frac{35}{100} \times 1460\) moles of \(HCl =\frac{35 \times 1460}{100 \times 36.5}\) So molarity \(=\frac{35 \times 1460}{100 \times 36.5}=14 \,M\)
