Chapter 3: Q23P (page 131)

Cisplatin(right) or platinol, is used in the treatment of certain cancers.

Calculate

  1. The moles of compound in 285.3 g of cisplatin;
  2. The number of hydrogen atoms in 0.98 mol of cisplatin.

Short Answer

Expert verified
  1. The moles of compound in 285.3 g of cisplatin is 0.951 mol
  2. The number of hydrogen atoms in 0.98 mol of cisplatin is3.54×1024atoms

Step by step solution

01

Step 1: Definition of moles

A standard scientific unit for measuring large quantities of very small entities, such as atoms, molecules or other specified particles

02

Calculations of moles of compound in 285.3 g of cisplatin

The molar mass of cisplatin is 300.06gmol

Moles of cisplatin=285.3gcisplatin(molcisplatin300.06gcisplatin)

Moles of cisplatin=0.951molcisplatin

03

Calculations of number of hydrogen atoms in 0.98 mol of cisplatin

Number of H atoms=0.98molcisplatin(6molHatoms1molcisplatin)(6.022×1023molHatoms)

Number of H atoms=3.54×1024atoms

Chromium(III) oxide reacts with hydrogen sulfide (H2S)gas to form chromium(III) sulfide and water: Cr2O3(s)+3H2S(g)→Cr2S3(s)+3H2O(I)

To produce 421 g of Cr2S3,

(a) How many moles of Cr2O3are required?

(b) How many grams of Xr2O3are required?

The effectiveness of a nitrogen fertilizer is determined mainly by its mass % N. Rank the following fertilizer, most effective first: potassium nitrate; ammonium nitrate; ammonium sulfate; urea,CO(NH2).

Citric acid (right) is concentrated in citrus fruits and plays a central metabolic role in nearly every animal and plant cell. (a) What are the molar mass and formula of citric acid? (b) How many moles of citric acid are in 1.50 qt of lemon juice (d = 1.09 g/mL) that is 6.82% citric acid by mass?

Menthol (m = 156.3 g/mol), a strong-smelling substance used in cough drops, is a compound of carbon, hydrogen, and oxygen. When 0.1595 g of menthol was subjected to combustion analysis, it produced 0.449 g of CO2 and 0.184 g of H2O. What is menthol’s molecular formula?

Lead(II) chromate (PbCrO4) is used as the yellow pigment in traffic lanes, but is banned from house paint because of the risk of lead poisoning. It is produced from chromite (FeCr2O4), an ore of chromium:

4FeCr2O4(S)+8K2CO3(aq)+7O2(g)→2Fe2O3(s)+8K2CrO4(aq)+8CO2(g)

Lead(II) ion then replaces the K+ ion. If a yellow paint is 0.511% PbCrO4 by mass, how many grams of chromite are needed per kilogram of paint?
