1297 grams of ore are needed to obtain 454.0 grams of Fe.

As the iron ore sample if found to be 35 percentage by mass

It means 35g of iron is present in 100g of ore.

1g of iron is present in 100/35 g of ore

And 454.0 g of iron is present in 100 × 454 / 35

         = 1297.14 or 1297 grams (approx.)

The mass percent is calculated by dividing the mass of the compound or solute by the mass of the element or solute. A percent is obtained by multiplying the result by 100.

The formula for an element's percentage in a compound is as follows:

mass percent is calculated by multiplying the mass of the element in one mole of the compound by one hundred.

A solution follows this formula:

(gm of solute / gm of solute plus solvent) × 100 equals mass percent.

or

(gm of solute/grams of solution) x 100 Equals mass percent

Hence, 1297 grams of ore are needed to obtain 454.0 grams of Fe.

It refers to all technological tools or apparatus utilized to protect human life. Medical equipment such as an insulin pump, a wireless brain sensor, a blood glucose meter, a digital thermometer, pulse oximeters, smart inhalers, etc the tools which had helped patients receive better medical treatment.

Effects of Medical technology:

Medical technology, nevertheless, can potentially cause issues for the patient like:

1. <u><em>Impersonal treatment</em></u>: When a healthcare professional uses technology too frequently, they could spend less time getting to know the patient as a person and more time dealing with the equipment.

2. <u><em>Harmful health impacts</em></u>: Surgery, radiation therapy, and chemotherapy are a few examples of treatments that might be advantageous but also have risks.

3. <u><em>Higher expenditures</em></u>: Due to the research and marketing required to bring new technologies to market and to generate a profit for their creators and manufacturers, they may result in increased patient costs.

4. <u><em>Potential for overuse:</em></u> The use of a technology or new product by a medical professional may be encouraged by the manufacturer, regardless of whether it is in the patient's best interest.

5. <u><em>Privacy violation</em></u>: Electronic medical records (EMR), for example, collect and manage patient information. This new technology is convenient, but it also has the potential to be misused, compromising patient privacy and personal data.
