How many moles of solute are present in 2 L of a 0.5 M solution?

Explanation opens after your attempt
Correct Answer

A. 1 मोल1 mol

Step 1

Concept

Molarity = moles/litre, so moles = molarity × volume.

Step 2

Why this answer is correct

Moles = 0.5 × 2 = 1 mol.

Step 3

Exam Tip

When molarity and volume are given, multiply to find moles. चरण 1: मोलरता = मोल/लीटर, इसलिए मोल = मोलरता × आयतन। चरण 2: मोल = 0.5 × 2 = 1 मोल। चरण 3: जब मोलरता और आयतन दिए हों, गुणा करके मोल निकालें।
