Answer:

0.174kg of Ore are required

Explanation:

The ore of 37.3% in nickel by mass means that <em>in 100g of ore there are 37.3g of nickel. </em>As we need to obtain 65g of nickel we can convert this mass to mass of ore using the conversion factor (100g Ore / 37.3g Nickel) as follows:

65g of nickel * (100g Ore / 37.3g Nickel) = 174g of Ore are needed to have 65.0g of nickel. In kilograms:

174g Ore * (1kg / 1000g) =

<h3>0.174kg of Ore are required</h3>
