Answer:
The volume will goes to decrease.
Explanation:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
when pressure is going to increase the volume will goes to decrease and vice versa.
Consider the initial volume is 10 L at initial pressure of 15 atm when pressure is increased to 30 atm the volume will be,
Now we will put the values in formula,
P₁V₁ = P₂V₂
15 atm × 10 L = 30 atm × V₂
V₂ = 150 atm. L/ 30 atm
V₂ = 5 L
Answer:
simple microscope has only one lens
:)
Answer:
a. .125 mol b. 7.25g
Explanation:
a. To get the moles multiply the volume by the molarity.
.5L*.25M=.125mol NaCl
b. The molar mass is provided so multiply the moles by the molar mass to get the amount of grams of nacl.
.125mol*58molar mass=7.25g nacl to make the solution
A- elements have only one type of atom but compounds have multiple
