Answer :
The mass (g) of a 257 ml sample with a specific gravity of 1.75 is 449.75
Calculation ,
The Formula of specific gravity ( when density of the water is 1g/ml ) is given as ,
specific gravity = density of an object
Density of an object can be computed using the formula :
Density = mass/ volume
Specific gravity = mass/volume
From there we can drive a formula for mass by transposing volume to the other side of the equation ,
volume × specific gravity = mass
mass = 1.75 × 257 ml = 449.75 gram
