32g of oxygen , temperature 293k has pressure of 230 kpa , what must be volume ?

Explanation:

Step 1. Calculate the moles of oxygen.

Step 2. Calculate the volume of oxygen

We can use the Ideal Gas Law:

pV = nRT

V = nRT/p

(a) Data

p =230 kPa

R = 8.314 kPa·L·K⁻¹mol⁻¹

T = 293 K

(b) Calculation

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
