Mikayla found the mass of a salt and water
solution using a digital scale. The total mass of the
solution was 105 grams. If the salt she added was
0.1 grams, what was the mass of the water before
she added the salt?



Answer :

Let m be the mass of the water, we know that we added 0.1 g of salt and that the solution has a mass of 105; then we have:

[tex]\begin{gathered} m+0.1=105 \\ m=105-0.1 \\ m=104.9 \end{gathered}[/tex]

Therefore, the mass of the water is 104.9 grams
