<span>(0.058 mol I2)(253.808 g/mol I2) = 14.721 g of I2 </span>
<span>So that's the mass of I2: 14.721 g </span>
<span>Percentage is the mass of solute/(mass of solute + mass of solvent) </span>
<span>14.721/(14.721g + 105 g) </span>
<span>14.721/119.721 </span>
<span>=0.123 or 12.3%

Answer:
mass drum (filled) = 198.083 Kg ( 436.306 Lb )
Explanation:
⇒ mass drum = 75.0 Lb * ( 454 g / Lb) = 34050 g ( 34.05 Kg )
⇒ volume drum = 55.0 gal * ( 3.78 L/gal ) = 207.9 L
⇒ density CH3CH2OH = 0.789 Kg/L
⇒ mass drum (filled) = 34.050 Kg + ( 207.9 L * 0.789 Kg/L )
⇒ mass drum (filled) = 34.050 Kg + 164.03 Kg
⇒ mass drum (filled) = 198.0831 Kg
Answer:
0.022
Explanation:
milliter (ml) = 1 cubic centimeter (cc)= 0.001 liters (l) = 0.000001 cubic meters (m3).
1 ml = 0.061024 cubic inches (in3) ; 1 in3 = 16.4 ml.
1 ml = 0.000035 cubic feet (ft3); 1 ft3 = 28,317 ml.
1 ml = 2.64 x 10-4 U.S. gallons (gal); 1 gal = 4.55 x 103 ml.
