To determine how much salt you would get if you evaporate all the water from an 80-gram solution with a 35% salt concentration, you can follow these steps:
1. Calculate the mass of the salt in the solution:
\[ \text{Mass of salt} = \text{Total mass of solution} \times \text{Concentration of salt} \]
Given that the total mass of the solution is 80 grams and the concentration is 35% (which can be written as 0.35 in decimal form):
\[ \text{Mass of salt} = 80 \text{ grams} \times 0.35 \]
\[ \text{Mass of salt} = 28 \text{ grams} \]
2. Since you are evaporating all the water, the amount of salt obtained will be the same as the mass of salt calculated above.
Therefore, if you evaporate all the water from an 80-gram solution with a 35% salt concentration, you would get 28 grams of salt.
How much salt would you get if you evaporate all the water from:
80 grams from a 35% salt solution
