Question

A) A fast-food restaurant makes double cheeseburgers using one hamburger roll, two quarter-pound patties of beef, one slice of cheese, a fourth of a tomato, and 15 g of shredded lettuce. At the start of the day, the restaurant manager has 18 dozen rolls, 38 lb of beef patties, 4 packages of sliced cheese containing 65 slices each, 49 tomatoes, and 3 kg of lettuce. Which ingredient will run out first, and how many cheeseburgers can be made?

B) Determine the molecular formula and calculate the molar mass (in g/mol) of arginine, the essential amino acid. The formula should be entered as CwHxNyOz, followed by other element if any.

Explanation / Answer

Ans B:-

Molecular folmula for arginine is C6H14N4O2

Molar mass :-

C=6 * 12 = 72;

H=14 * 1 = 14;

N=4 * 14 = 56;

O=2 * 16 = 32

Thus, 72+14+56+32 = 174 g/mol
