Mole of any substance = 6.022 E23 particles 1) Sucralose is an artificial sweetener and sugar substitute. The majority of ingested sucralose is not broken down by the body, so it is noncaloric. It has a molar mass of 398 g/mole. A packet of Splenda (aka sucralose) contains 12 milligrams of sucralose. What mass is this in grams?

He should get it peer reviewed and publish it, then let other scientists try to reproduce his results.

Explanation:

i took the quizz

your answer would be a. 12.5 kg

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
