Determine whether the statements given below are true or false. (a) The mass of an atom can have the unit mole. (b) In N204, the mass of the oxygen is twice that of the nitrogen. (c) One mole of chlorine atoms has a mass of 35.45 g. (d) Boron has an average atomic mass of 10.81 amu. It has two isotopes, B-10 (10.01 amu) and B-11 (11.01 amu). There is more naturally occurring B-10 than B-11. (e) The compound C 6 H 12 O 2 N has for its simplest formula C 3 H 6 ON 1/2 . (f) A 558.5-g sample of iron contains ten times as many atoms as 0.5200 g of chromium. (g) If 1.00 mol of ammonia is mixed with 1.00 mol of oxygen the following reaction occurs, 4NH 3 ( g ) + 5O 2 ( g ) → 4NO ( g ) + 6H 2 O ( l ) All the oxygen is consumed. (h) When balancing an equation, the total number of moles of reactant molecules must equal the total number of moles of product molecules.

What is the molecular weight of sugar, C6H12O6 in atomic mass units?
And If you had one mole of sugar molecules, how much would it weigh?
Boron trifluoride is used as a catalyst in the synthesis of or-ganic compounds. When this compound is analyzed by massspectrometry several different 1+ ions form, including ions representing the whole molecule as well as molecular fragments formed by the loss of one,two, and three F atoms. Given that boron has two naturally occurring isotopes, ¹⁰B and ¹¹B, and fluorine has one, ¹⁹F, calculate the masses of all possible 1+ ions
