Explanation / Answer
Post one more question to get the remaining answers
1) 1 Euro = $1.095
1 Gallon = 3.78541 L
Price in Euros per liter = $1.649/gallon * 1 gallon/3.75841 * 1 Euro/1.095$
=> 0.4006 Euros/Liter
2) Volume of Tin = (15 * 10^(-5) * (25 * 10^(-2) * (1.75) = 6.5625 * 10^(-5) m^3
Density of Tin = 47 * 10^(-3) Kg/ 6.5625 * 10^(-5) m^3 = 4700/6.5625 Kg/m^3 = 716.19 Kg/m^3
3) Density = Mass/Volume
Nass = 0.179 mg/cm^3 * 5.45 * 1000cm^3/1L
=> 0.179 * 5.45 gms
=> 0.97555 grams
