Algebra.Com's Answer #788116 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! The total mass is 2400 g, and the density of the mixture is \n" ); document.write( "D = 2400 g/1000 cm^3 = 2.4 g/cc \n" ); document.write( "The mass of liquid 1 is m1 = d1*V1 where d1 and V1 are the density and volume of #1 \n" ); document.write( "The mass of liquid 2 is m2 = d2*V2 \n" ); document.write( "Given: d1 = 2, d2 = 3 \n" ); document.write( "We know that: m1 + m2 = 2400 and V1 + V2 = 1000 \n" ); document.write( "Thus m1 = 2V1 \n" ); document.write( "2400 - m1 = 3(1000 - V1) -> 2400 - 2V1 = 3000 - 3V1 -> V1 = 600 \n" ); document.write( "Hence V2 = 400, m1 = 2*600 = 1200, m2 = 3*400 = 1200 \n" ); document.write( "Ans: V1 = 600 cm^3, V2 = 400 cm^3, m1 = m2 = 1200 g\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
