If you’ve been vaping for a while now, you may be craving some new vape juice flavors to try with your favorite RDA, RTA, or Box Mod.
You might find that ordering large batches of your all day vape juice flavors can prove a bit on the expensive side, particularly if your tastes run toward the premium e juice priced at over $20 per bottle.
Surely there must be a better way than taking out payday loans to get your hands on that Peanut Butter Crunch-flavored creation you just have to have in your sub-ohm tank?
Fortunately, when you know how to make homemade vape juice it can be a fun and fascinating hobby that has the delightful side effect of saving you loads of cash using cheap vape juice.
Many people hear “diy vape juice” and get visions of a mad scientist in a dank lab constantly flirting with explosion by mixing volatile chemicals while laughing insanely.
The reality is that it’s relatively easy to learn how to make your own vape juice at home, and we’re going to attempt to cover all the facets involved.
Are you interested in making your own e juice?

Explanation:
Given
The wavelength of the light is 
Energy associated with a photon(light) is given by 
where, 


Therefore, the energy associated with the light is 
Answer:
Mass= 2.77g
Explanation:
Applying
P=2.09atm, V= 1.13L, R= 0.082, T= 291K, Mm of N2= 28
PV=nRT
NB
Moles(n) = m/M
PV=m/M×RT
m= PVM/RT
Substitute and Simplify
m= (2.09×1.13×28)/(0.082×291)
m= 2.77g
Answer:
Explanation:
The equation of above line , y = 0.0005x+ 0.458
This can be compared with y = mx+c
Hence slope, m = 0.0005 and Y-intercept, c = 0.458
Or it can be plotted manually where straight line has to be drawn touching maximum number of data points. After drawing a straight linear line, we need to take any two points from the straight line and slope is calculated
Slope,

and y -intercept is calculated using extraplotting backwards such that it touches the Y-axis. the point where straight line touches Y-axis is Y-intercept (c).
Plot the average cell potentials E (y-axis) vs T (x-axis). image attached
