Answer:
83.000
Step-by-step explanation:
8.3 × 10⁴
= 8.3 × (10 × 10 × 10 × 10)
= 8.3 × (100 × 10 × 10)
= 8.3 × (100 × 100)
= 8.3 × 10.000
= 83.000
Conclusion:
The result of 8.3 × 10⁴ is 83.000

I think it is A rocky material; icy material
Yes. As long as the ratio of solute and solvent is same for both solution, the solution has the same concentration. for example, solution A has 2 ml of water, and 1 ml of sucrose. Solution B has 4ml of water and 2ml of sucrose. Both has a ratio of water to sucrose by 2 : 1. they have the same concentration of 50% sucrose.
