Answer:
The answer to your question is mass = 455.6 grams
Explanation:
Data
Dimensions = 68.6 yd x 12 in x 0.00035 in
density = 2.70 g/cm³
mass = ?
Process
1.- Convert dimensions to cm
1 yd ---------------- 91.44 cm
68.6 yd ------------ x
x = (68.6 x 91.44) / 1
x = 6227 cm
1 in ----------------- 2.54 cm
12 in --------------- x
x = (12 x 2.54) / 1
x = 30.48 cm
1 in -------------- 2.54
0.00035 in ------------- x
x = (0.00035 x 2.54) / 1
x = 0.000889 cm
2.- Find the volume of the foil
V = 6227 x 30.48 x 0.000889
V = 168.73 cm³
3.- Find the mass of the foil
mass = density x volume
mass = 2.70 x 168.73
mass = 455.6 g
We have:
V = 55.0 gallons x 3.78541 = 208 L
P = 16500 kPa
T = 23 + 273.15 = 296.15 K
Part A) From the equation PV =
we get:
mass of O₂ = (16500 kPa x 208 L x 32 g/mol) / (8.314 x 296.15 K)
= 44.6 Kg
Part B) at STP we have:
T = 273.15 K and P = 101.3 kPa
so from PV = mRT / M
V = (44600 x 8.314 x 273.15) / (32 x 101.3)
= 31248 L
Part C) From the equation PV = mRT / M
we get
T = (150 atm x 101.3 kPa / atm x 208L x 32g/mol) / (8.314 x 44600)
= 272.8 K
Part D) we have:
T = 24 + 273.15 K = 297.15 K
so from PV = mRT / M, we get
P = (44600 x 8.314 x 297.15) / (32 x 55)
= 62464 kPa
Answer:
Even small amounts of radiation over a prolonged period of time can be dangerous.
Explanation:
We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes
My part of the atom, I'm guessing you are referring to the protons, neutrons, and electrons.
The smallest of these three is the electron.
