The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
Answer:
0.72727272727 or 0.73
Step-by-step explanation:
To get that all you have to do is divide 8 by 11. So 8 divided by 11 equals 0.72727272727 which would round up to 0.73
Answer:
is there a graph?
Step-by-step explanation:
Answer:
Step-by-step explanation:
change in graph=(y2-y1)/(x2-x1)=(0.25-2)/(4.5-2.5)
=-1.75/2=-0.875
The answer is D
