(a)
Interpretation:
The chemical notation
Concept Introduction:
The composition of a chemical compound can be presented in a very precise was with the use of chemical formula. Chemical formula uses chemical symbols of the elements that is present in the compound and numerical subscripts that represent how many number of atoms of each element is present in the compound.
(a)
Answer to Problem 1.76EP
Explanation of Solution
Given chemical notation is
The total number of atoms present in the chemical formula is found by summing up the subscript present in the chemical formula.
Therefore, there is one atom in the given chemical formula.
(b)

- Acetaminophen, whose structure is drawn below, is the active ingredient in some nonprescription pain killers. The recommended dose for an adult is two 500-mg caplets. How many molecules make up one dose of this drug?arrow_forwardSketch a magnified view (showing atoms/molecules) of each of the following and explain: a. a heterogeneous mixture of two different compounds b. a homogeneous mixture of an element and a compoundarrow_forwardMa huang, an extract from the ephedra species of plants, contains ephedrine. The Chinese have used this herb for more than 5000 years to treat asthma. More recently, ephedrine has been used in diet pills that can be purchased over the counter in herbal medicine shops. However, very serious concerns have been raised regarding these pills following reports that their use led to serious heart problems. (a) A molecular model of ephedrine is drawn below. From this determine the molecular formula for ephedrine and calculate its molar mass. (b) What is the weight percent of carbon in ephedrine? (c) Calculate the amount (moles) of ephedrine in a 0.125 g sample. (d) How many molecules of ephedrine are there in 0.125 g? How many C atoms?arrow_forward
