Question

Aspartame is an artificial sweetener that is 160 times sweeter than sucrose (table sugar) when dissolved in water. It is marketed as Nutra-Sweet. The molecular formula of aspartame is C14H18N2O5.

a- Calculate the molar mass of aspartame.

b- what amount (moles) of molecules are present in 10.0 g aspartame?

c-Calculate the mass in grams of 1.56 mol aspartame.

d-What number of molecules are in 5.0 mg aspartame?

e-What number of atoms of nitrogen are in 1.2g aspartame?

f-What is the mass in grams of 1.0 X 10^9 molecules of aspartame?

g- What is the mass in grams of one molecule of aspartame?

Answer 1

a) (12X14)+(1X18)+(2X14)+(16X5)= 294M

b) 10.0g/ 294= 0.034 mols

c) 1.56 X 294= 458.64grams

d) 5mg= 5000 grams, 5000/ 0.034= 147058.8235/ 294= 500 molecules

e) 1.2/ 0.034= 35.294, 35.294/ 39 (total number of atoms e.g ad up all the numbers in C14H18N2O5 gives 39) = 0.905X2= 1.81 atoms of nitrogen

f) 1.0 x10^9 X 0.034= 34X10^6 grams (34,000,000g)

g)39X 0.034= 1.326 grams

Please check the answers, especially the last 3 (e,f,g)

hope this helps..
