A Solution has a density of 1.50g/mL How many grams are needed to obtain 10.0mL of solution
2 answers:
Answer: The required number of grams needed is 15 grams.
Step-by-step explanation: Given that a solution has a density of 1.50 g/mL.
We are to find the number of grams that are needed to obtain 10.0 mL of solution.
We will be using the UNITARY method to solve the problem.
We have
Number of grams needed o obtain 1 mL of solution = 1.50 gm.
So, number of grams needed to obtain 10.0 mL of solution is given by
Thus, the required number of grams needed is 15 grams.

Answer:
Rabbit is faster than bear.
Step-by-step explanation:
Speed of rabbit or bear is determined by their rate of change of their distances with time.
The distance covered by rabbit in hours is given as:
The above equation is of the form , where,
is the rate of change of
with
.
Therefore, the rate of change of rabbit's distance with time is 30 mi/h.
Now, from the graph, the slope is given as the rise over run.
Rise is 50 miles and run is 2 miles.
So, rate of change of bear's distance with time is,
Now, 30 is greater than 25. So, rabbit is faster than bear.
