Calculate the molality of a solution prepared by dissolving 10.0 g of NaCl in 600g of
water.

0.417 m

Explanation:

In order to calculate the molality of a solution prepared by dissolving 10.0 g of NaCl in 600g of  water, we need to follow a series of steps.

Step 1: Calculate the moles of NaCl (solute)

The molar mass of NaOH is 40.00 g/mol. The moles corresponding to 10.0 grams are:

Step 2: Convert the mass of water (solvent) to kilograms.

We will use the relation 1 kg = 1000 g.

Step 3: Calculate the molality of the solution

We use the definition of molality.

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
