So, density is defined as mass per unit volume. This is generally given as grams per milliliter. So, we will find the grams (mass) and the volume (mls) and then determine density.
mass of salt = 52.5 g
mass of water = 3.45 L x 1000 ml /L = 3450 ml and if we use 1.0 g/ml as the density of water, we have 3450 g
Total mass of salt plus water = 52.5 g + 3450 g = 3502.5 g
Total volume in mls = 3450 mls
Density = mass/volume
Density = 3502.5 g / 3450 mls
Density = 1.02 g/ml (to 3 significant figures)
