Question

We add 5.0 g of sugar to 100 mL of water.
What is the mass of the solution?

Answer 1

The mass of the solution : 105 g

Further explanation

Given

5 g sugar

100 ml water

Required

The mass of the solution

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density  

m = mass  

v = volume  

Density of water = 1 g/ml

So mass of water :

= density x volume

= 1 g/ml x 100 ml

= 100 g

So total mass of solution :

=mass sugar+mass water

= 5 g + 100 g

= 105 g
