The rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10²
<h3>What are significant figures?</h3>
Significant figures are figures that contribute to the general and overall value of the whole number.
Significant figures or digits are specifically meaningful with respect to the precision of a measurement.
Although, the original number given in this question has 9 significant figures, the number; 300.235800 can be rounded up to four significant figures as follows:
- Decimal notation: 300.2
- No. of significant figures: 4
- No. of decimals: 1
- Scientific notation: 3.002 × 10²
Therefore, the rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10².

It’s c I believe because it says 209 years to complete an orbit so hint yourself ?.....
Answer:
0.83 mL
Explanation:
Given data
- Initial concentration (C₁): 12 M
- Final concentration (C₂): 1.0 M
- Final volume (V₂): 10.0 mL
We can calculate the initial volume of HCl using the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 1.0 M × 10.0 mL / 12 M
V₁ = 0.83 mL
The required volume of the initial solution is 0.83 mL.
