The slandard for safe drinking water is a maximum of 1.6 milligrams of copper per liter of waler. A sludy was conducted on a sample of 6 liters of water. The analysis revealed 7.34 miligrams of copper in the sample. Is the water safe or nol? How much did tho amount of copper per liter in the sample differ from the maximum of the standard? Is the water sale? No Yes The difference is milligram per fiter. (Round to the nearest thousandth as needed.)

To determine if the water is safe or not, we need to compare the amount of copper found in the sample with the maximum allowed by the standard. Given: - Standard for safe drinking water: 1.6 milligrams of copper per liter of water. - Sample size: 6 liters of water. - Amount of copper found in the sample: 7.34 milligrams. First, let's calculate the amount of copper per liter in the sample: \[ \text{Copper per liter} = \frac{7.34 \text{ milligrams}}{6 \text{ liters}} \] Next, we will compare this value with the maximum allowed by the standard to determine if the water is safe or not. Finally, we will calculate the difference between the amount of copper per liter in the sample and the maximum allowed by the standard. Calculate the value by following steps: - step0: Calculate: \(\frac{7.34}{6}\) - step1: Convert the expressions: \(\frac{\frac{367}{50}}{6}\) - step2: Multiply by the reciprocal: \(\frac{367}{50}\times \frac{1}{6}\) - step3: Multiply the fractions: \(\frac{367}{50\times 6}\) - step4: Multiply: \(\frac{367}{300}\) The amount of copper per liter in the sample is approximately 1.22 milligrams. Now, let's calculate the difference between the amount of copper per liter in the sample and the maximum allowed by the standard: \[ \text{Difference} = 1.6 \text{ milligrams} - 1.22 \text{ milligrams} \] Let's calculate the difference. Calculate the value by following steps: - step0: Calculate: \(1.6-1.22\) - step1: Subtract the numbers: \(0.38\) The difference between the amount of copper per liter in the sample and the maximum allowed by the standard is 0.38 milligrams per liter. Since the amount of copper found in the sample (1.22 milligrams per liter) is less than the maximum allowed by the standard (1.6 milligrams per liter), the water is safe.
