Calculate the volume in liters of a 1.8m sodium chloride solution that contains 175. g of sodium chloride (naci). round your answer to 2 significant digits.

The volume of the NaCl solution is 1.7 L

Explanation:

Step 1: Data given

Molarity of sodium chloride = 1.8 M

Mass of sodium chloride = 175 grams

Molar mass of sodium chloride = 58.44 g/mol

Step 2: Calculate moles sodium chloride

Moles NaCl = mass NaCl / molar mass NaCl

Moles NaCl = 175.0 grams / 58.44 g/mol

Moles NaCl = 2.995 moles

Step 3: Calculate volume of solution

Molarity = moles / volume

Volume = moles NaCl / molarity

Volume = 2.995 moles / 1.8 M

Volume = 1.66 L ≈ 1.7 L

The volume of the NaCl solution is 1.7 L

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
