Astore is offering a 20% discount on all sales over $50. if you purchase a shirt and a pair of jeans for $62.50, what is the amount of the discount you would receive? a. $10.00 b. $12.50 c. $15.63 d. $50.00

let's  assume that the f₂  gas  has ideal gas behavior. 

then we can use ideal gas formula,pv = nrt where, p is the pressure of the gas (pa), v is the volume of the gas (m³),  n is the  number of moles of gas (mol), r is the universal gas constant ( 8.314 j mol⁻¹ k⁻¹) and t is temperature in kelvin.

moles = mass / molar mass

molar mass of f₂ =  38 g/mol

mass of  f₂  = 76 g

hence, moles of f₂ = 76 g / 38 g/mol = 2 mol

p = ? v =  1.5 l = 1.5 x 10⁻³  m³

n = 2 mol

r =  8.314 j mol⁻¹ k⁻¹ t = -37 °c = 236 k by substitution,

p x  1.5 x 10⁻³  m³ = 2 mol x 8.314 j mol⁻¹ k⁻¹ x 236 k

                          p = 2616138.67 pa

                          p =  25.8 atm = 26 atm

hence, the pressure of the gas is 26 atm.

answer is "a".

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
