Atoms cannot be created or detroyed, only rearranged.
Answer:
0.228 L is the volume that the gas occupies after it is driedand stored at STP.
Explanation:
Pressure of the wet gas = 
1 atm = 760 Torr
Pressure of water vapor = p = 0.0372 atm
Pressure of gas = 
Volume of wet gas = 
1 mL = 0.001 L
Temperature of the wet gas = 
Pressure of dry gas at STP = 
Temperature of the dry gas at STP ,
Volume of dry gas at STP = 
Using combined gas law:



0.228 L is the volume that the gas occupies after it is driedand stored at STP.
CaCl₂ → Ca²⁺ + 2Cl⁻
∑=1+2=3
D) 3 mol
Answer:
Melting Is when a substance is actually melting and melting point is a point at which a substance is able to melt.
A balance in a lab measures the weight of a substance or object.
Weight is the mass of the body x the gravitation pull on the mass of the object.
So the mass of the object can be found by dividing the weight by gravitational constant.
The gravitational constant on earth is 1. so if a balance says that a substance weighs 300g then its mass is also 300g on earth because 300/1 = 300.
Hope that helps :)
