A 3.00 g sample of a go and agent if 1.94 g of sample are from silver what is the percent tack and percentage gave in sample
The correct answer and explanation is:
Correct Answer:
- Percent of silver (Ag) in the sample = (1.94 g / 3.00 g) × 100 = 64.67%
- Percent of other agent (non-silver) = 100% − 64.67% = 35.33%
Explanation:
To find the percentage composition of substances within a mixture, you compare the mass of each component to the total mass of the sample. In this case, the total sample weighs 3.00 grams, and out of that, 1.94 grams is made up of silver (Ag).
To determine the percentage of silver, divide the mass of silver by the total mass of the sample and multiply the result by 100 to convert it into a percentage: 1.943.00×100=64.67%\frac{1.94}{3.00} \times 100 = 64.67\%
This tells us that 64.67% of the sample is composed of silver. The rest of the sample is made up of other substances or agents.
To find the percentage of the other agent, subtract the percentage of silver from 100%: 100%−64.67%=35.33%100\% – 64.67\% = 35.33\%
So, the non-silver portion of the sample, or the other agent, makes up 35.33% of the total mass.
This kind of calculation is common in chemistry when analyzing the composition of alloys, ores, or mixtures. Understanding what portion of a sample is made up of a specific element or compound is crucial in material science, metallurgy, and analytical chemistry. It helps in determining the quality or value of a sample, especially when precious metals like silver are involved.
