Answer:
Answer:- 1467 K
Solution:- It asks to calculate the kelvin temperature of the light bulb. Looking at the given info, it is based on ideal gas law equation, PV=nRT.
The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.
<h3>What is conversion factor?</h3>
Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.
Given that quantity of salt solution = 2.50 L
We know that, 1 L = 1.06 qt
Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:
2.50L = 2.50L × 1.06qt/L = 2.65qt
Hence required value is 2.65qt.

Answer:
1. 12 molecules
2. 10 grams
3. ?
Explanation:
for number one, you simply. multiblu the 02 by 6 an that is 12, the same goes for number two. now for the third one i di not know. i am sorry and i hope this helps.
% m/v of the solution = 0.2%m/v
<h3>Further explanation</h3>
or
% m/v = g solute / 100 ml solution
Concentration : 2 g sodium borate / L water
For 10 L⇒20 g Sodium borate
A) I-
An anion is is a negatively charged ion. :)
