Solving these simple Chemistry problems?
1. A packing material has a density of 12.8kg/m^3. How many lbs of this material are needed to fill 2.00 ft^3 box? (1lb = 454g, 1 in.= 2.54 cm, 1ft = 12 in.)
2. A 14-karat gold ring contains 58.3% gold and weighs 12.41 g. If gold sells for $276.00/ounce, what is the value of the gold in the ring? (1 oz = 28.35 g)
3. The density of gold is 19.3 g/cm^3. A 3.4 mg piece of gold is hammered into a square that is 8.6 x 10^-6 cm thick. What is the length of a side of the square in cm?
1) 2.00 ft^3 * ((12)^3 in^3)/1ft^3 = 3456 in^3
3456 in^3 * ((2.54)^3 cm^3)/1in^3 = 56634 cm^3
56634 cm^3 * (1 m^3)/(10^6 cm^3) = 5.6634*10^-2 m^3
12.8 kg / m^3 * 5.6634*10^-2 m^3 = 0.725 kg
0.725 kg * 1000 g / 1 kg = 725 g
725 g * 1 lb / 454 g = 1.597 lb
2) 12.41 g * 0.583 = 7.24 g gold
7.24 g * 1 oz / 28.35 g = 0.26 oz
0.26 oz * $276.00 / 1 oz = $71.76
3) 3.4*10^-3 g / (19.3 g/cm^3) = 1.8*10^-4 cm^3
1.8*10^-4 cm^3 / 8.6*10^-6 cm = 20.93 cm^2
sqrt(20.93)= 4.6 cm
