0/1 An unknown liquid has a density of 5.45 g/ml. It is placed into a graduated
cylinder with a mass of 38 grams. The total mass of cylinder and liquid is 103
grams when the liquid and the graduated cylinder are placed on the balance
together. What is the volume of the liquid? *
0.084 mL
11.93 mL
354.25 mL
37.5 mL

answer; talc and gypsum;

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
