(mark the one best answer)
A.
Red solution density is1.00 g/ml and the blue solution density is 0.83 g/ml
B.
Green solution density is 1.06 g/ml and blue solution density is 1.20 g/ml
C.
Green solution density is 0.94 m=g/ml and yellow solution density is 0.88 g/ml
D.
Blue solution density is 1.00 g/ml and Red solutio density 1.20 g/ml
1 answer:
Answer:
B. Green solution density is 1.06 g/ml and blue solution density is 1.20 g/ml
Explanation:
Density is given as,
D = Mass / Volume
Red Solution,
D = 25 g / 25 mL
D = 1 g/mL
Green Solution,
D = 26.5 g / 25 mL
D = 1.06 g/mL
Yellow Solution,
D = 28.2 g / 25 mL
D = 1.128 g/mL
Blue Solution,
D = 30 g / 25 mL
D = 1.20 g/mL

The answer is D because it sounds like the most ethical answer. The other choices are wrong because the could possibly hurt someone or an animal.
Answer:
Answer:
the molar mass of the element
The answer is B 5.40 x 10^14 Hz
Answer:
12.5g
Explanation:
1. Percentage of solution = 5.
2. Mass of solution = 250g.
3. = Mass of solute / 250 x 100.
4. = 5 x 250 / 100.
5. = 12.5g.
