Answer:
7.8g of potassium
Explanation:
To solve the problem you need to know that in 100g of apples there are 170mg of potassium.
First you should convert units to work all the quantities in the same units, so lets to convert all to kg:
[tex]100gapples*\frac{1kg}{1000g}=0.1kgapples[/tex]
[tex]170mgpotassium*\frac{1*10^{-6}kg}{1mg}=1.7*10^{-4}kgpotassium[/tex]
Then lets to apply conversion factors to find the answer:
[tex]4.62kgapples*\frac{1.7*10^{-4}kgpotassium}{0.1kgapples}*\frac{1000g}{1kg}=7.8[/tex]g of potassium
