Answer:
0.67 cm³
Explanation:
We can solve this problem by using the <em>definition of density</em>:
We can rearrange the equation and isolate volume:
As we are given both <em>the mass and the density</em>, we can now<u> calculate the volume</u>:
- Volume = 13 g ÷ 19.3 g/cm³
Answer:
pH = 10.4
Explanation:
pH = -log [H⁺] = -log(4.1 x 10⁻¹¹) = -(-10.4) = 10.4
If you search the question up on google you may find the whole work sheet that’s what I used to do when I was in middle school!
The solute increased to the boiling point of the solvent. In shorter terms it's raising to the boiling point.
The rule of significant figures when multiplying numbers is that the number of significant figures of the product must be that of the least number of significant figures of the factors.
The factors are 2.2 which has 2 significant figures and 5.00 which has 3 significant figures. Therefore, the product must only have 2 significant figures.
The answer is B. 11 mm2
