In a 180 kilogram sample of ore, there was 3.2% of metal. How many kilograms of metal were in the sample?
what is .032(180) ?
To find the amount of metal in the sample, you can multiply the total weight of the sample by the percentage of metal.
1. Convert the percentage to a decimal by dividing it by 100:
3.2% = 3.2/100 = 0.032
2. Multiply the decimal by the total weight of the sample:
Metal weight = 0.032 * 180 kilograms
Metal weight = 5.76 kilograms
Therefore, there were 5.76 kilograms of metal in the sample.
To find the number of kilograms of metal in the sample, you can use the following formula:
Mass of metal = (Percentage of metal / 100) × Mass of ore
Plugging in the given values:
Mass of metal = (3.2 / 100) × 180 kg
Now, divide 3.2 by 100 to get the decimal value: 3.2 / 100 = 0.032
Mass of metal = 0.032 × 180 kg
Multiply 0.032 by 180 to get the mass of metal:
Mass of metal = 5.76 kg
Therefore, there are 5.76 kilograms of metal in the sample.
