There is 12 inches in 1 foot.
Divide 16 with 12 to get feet
16/12 = ~1.33 (rounded)
1.33 is your answer
hope this helps
Answer: The pH of solution is 10.
The pOH of the solution is 4.
Explanation:
pH is the negative logarithm of concentration of hydrogen ion.
As given concentration of acidic solution is 
. Therefore, pH of the solution is calculated as follows.
![pH = -log [H^{+}]\\= -log (1.00 \times 10^{-10})\\= 10](https://tex.z-dn.net/?f=pH%20%3D%20-log%20%5BH%5E%7B%2B%7D%5D%5C%5C%3D%20-log%20%281.00%20%5Ctimes%2010%5E%7B-10%7D%29%5C%5C%3D%2010)
The relation between pH and pOH is as follows.
pH + pOH = 14
pOH = 14 - pH
= 14 - 10
= 4
Thus, we an conclude that pH of solution is 10 and pOH of the solution is 4.
Answer:
0.97 × 10⁹ strontium atoms
Explanation:
if 1 pm is equal with 10⁻⁹ mm
then 215 pm are equal to X mm
X = (215 × 10⁻⁹) / 1 = 215 × 10⁻⁹ mm
Now the diameter of the strontium atom is twice the radius:
diameter = 215 × 10⁻⁹ × 2 = 430 × 10⁻⁹ mm
if 1 strontium atom have a diameter of 430 × 10⁻⁹ mm
then X strontium atom are needed to be laid said by side to span a distance of 419 mm
X = (419 × 1) / (430 × 10⁻⁹) mm = 0.97 × 10⁹ strontium atoms
