Answer:
gravity
Explanation:
Gravity is an example of the force of attraction between two objects that have mass.
Hello! Your answer will be C. If you need an explanation let me know!
To determine the amount of each solution that she should use, we do mass balance for the whole process. We let x be the amount the 65% salt and y the amount of the 90% salt. We do as follows:
The total mass should be equal to 150 oz.
x + y = 150
Doing a salt balance, we obtain the second equation:
.65x + .90y = 150(.85)
Solving for x and y, we obtain:
x = 30 oz
y = 120 oz
