Agas occupies 4.23 l at 2.25 atm. what is the volume at 3.46 atm?

Boyle's law gives the relationship between pressure and volume of gas.
It states that at constant temperature pressure in inversely proportional to volume. 
PV = k
where P - pressure V - volume and k - constant 
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
substituting the values in the equation 
2.25 atm x 4.23 L = 3.46 atm x V 
V = 2.75 L
new volume is 2.75 L

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
