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
