A student mixed 115 g of sugar, 350 g of water and 5 g of spices. What will be the mass of the solution?

jenyasd209 [6]

Answer:

$m_{solution}=470g$

Explanation:

Hello,

In this case, a solution is formed when a solute is completely dissolved in a solvent, thus, for this situation, the sugar is the solute and the water the solvent but in addition to them we find spices which are also considered in the total mass of the solution. In such a way, for computing the total mass we must add the mass of three constituents (115 g sugar, 350 g water and 5 g spices) as shown below:

$m_{solution}=115g+350g+5g\\\\m_{solution}=470g$

Best regards.
