Hello there!
In this case, by considering that the reaction between sodium hydroxide and hydrochloric acid is in a 1:1 mole ratio of these two reactants, we are able to use the following equation relating the concentration and volume of each one:
In such a way, by solving for the volume of the base, we will obtain:
Regards!
I suspect that the pressure of this change is constant therefore
The equation is used from the combined gas law. (When pressure is constant both P's will cancel out P/P = 1)
V/T = V/T
Initial Change
Initially we have 2L at 20 degress what temperature will be at 1L.
2/20 = 1/T
0.1 = 1/T
0.1T = 1
T = 1/0.1
T = 10 degress celsius.
Hope this helps if you won't be able to understand what is the combined gas law just tell me :).
The graduated cylinder is used to measure the volume of KOH and H2SO4 when accurate volume measurement is not required.
In the laboratory certain graduated apparatus are used to measure liquids. These graduated apparatus used to measure liquids include;
- burette
- pipette
- measuring cylinder
- Erlenmeyer flask
Sometimes, we are not really looking for a strictly accurate volume of liquid and we can use a graduated cylinder to measure the volume of liquid in such cases.
However, when we need to have strictly accurate volume measurement, we need a pipet or a buret.

Answer:
There are 1000 mg in 1. g
There are 1000 g in 1 kg
Each students needs 2,250 mg of clay
Explanation:
In order to determine the amount of how many kilograms to order, the teacher will need to find out the total mass of clay required by the students and then the teacher will have to convert the total mass to the units required for the purchase.
The teacher would have to find out how many milligrams make one kilogram as follows
1 kg = 1000 g
1 g = 1000 mg
Therefore, 2,250 mg = 2250/1000 g = 2.25 g
2.25 g = 2.25/1000 kg = 0.00225 kg.
