To take the percent by mass of this element, we use the formula:
% mass = (mass of element / mass of ore) * 100%
% mass = (47.5 g / (660 kg * 1000 g / kg)) * 100*
% mass = 7.20 x 10^-3 %
Answer: The mass percent of element in the ore is 0.0072 %
Explanation:
To calculate the mass percentage of element in ore, we use the equation:
[tex]\text{Mass percent of element}=\frac{\text{Mass of element}}{\text{Mass of ore}}\times 100[/tex]
Mass of element = 47.5 g
Mass of ore = 660 kg = 660000 g (Conversion factor: 1 kg = 1000 g)
Putting values in above equation, we get:
[tex]\text{Mass percent of element}=\frac{47.5g}{660000g}\times 100=0.0072\%[/tex]
Hence, the mass percent of element in the ore is 0.0072 %
