Answer #1

As we know

Molarity of a solution is - moles of solute per litre of solution,

thus Molarity = 2 moles of Nacl/ 1litre of water

which is= 2M

    Chemists often use molarity M, in moles/liter, to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure. However, the drawback of using molarity is that volume is a temperature-dependent quantity. As temperature changes, density changes, which affects volume. Volume markings for most laboratory glassware are calibrated for room temperature, about 20∘C. A 2.500×10−2M solution of NaCl in water is at 20.0∘C. The sample was created by...
