HW4 Solved Example
One more analytical chemistry help problem?
Calculate the percent yield of an analysis if 1.9365g of AgCl (MM 143.32 g/mol) was precipitated in a gravimetric experiment if 1.2000g of a soluble sample that contained 40.25% Cl- was used as the starting material.
Please show or talk me through as much work as possible.
40.25% of 1.2000 g = 0.4830 grams of Cl-
0.4830 grams of Cl- @ (143.32 g/mol AgCl) / 35.45 g/mol Cl = 1.9527 g AgCl
the percent yield of an analysis:
1.9365g of AgCl produced / 1.9527 g AgCl possible (X's 100) = 99.170% yield
it became a 4 sig fig problem with the "40.25%"
your answer is: 99.17%
Used Roche Chemistry Analyzers
Chemical analyzers find greater application in clinical laboratories, hospitals and other related fields. Chemistry analyzers are extensively used for homogenous immunoassays, STAT analyses, vitro analysis of chemical substances in blood and other body fluids. Both new and used models are available. New equipment is expensive whereas used models are available at half the price of new ones.
Roche Chemistry Analyzers for Optimum Functionality
Roche Diagnostics is a leading manufacturer offering a wide array of models with diverse features. Some of them are Roche Cobas Mira, Roche Hitachi 717 and Roche Integra 700. These feature standardized technology for flexible and efficient operation every time. These devices are fully automated with sample bar code capability. The Roche chemistry analyzer consists of an analytic unit with ISE and photometric measuring system and a control unit including CPU, printer, monitor and keyboard. It ensures easy to use test strips and develops results quickly. Some of the advanced versions of Roche chemistry analyzers are available with microprocessor controlled pipetting system. Such models can hold 4000 patient results at a time. Roche chemistry analyzers are available with optional features such as:
• Reagents, controls, and consumables may be available
• ISE module for sodium, potassium and chloride determinations
• Bidirectional interface
• Monochromatic , bi-chromatic , end point and kinetic essay types
• Liquid level and clot detection
• Random-access testing flexibility
• Provision for user to select tests, review results and program system parameters.
Assure Quality Products from a Reliable Dealer
Before choosing a used chemical analyzer, care must be taken to check its working condition. Chemical analyzers are available in a variety of models and prices from leading dealers. So choose a recognized dealer who can ensure used Roche chemistry analyzers in optimum working condition, with warranty at competitive prices.
