calculate the molecular weight of a substance which freezes forms a 7.00% by mass solution in water which freezes at -0.89°C.

C6H6 freezes at 5.5°C. At what temperature will a solution of 10 g of C4h10 in 200g of C6H6 freeze? The molal freezing point depression constant of C6H6 is 5.16°C/m?

Camphor, C16H16O which has a freezing point of 174°C, has a freezing point depression constant of 40.0°C/m. Explain the usefulness and the limitation of camphor as a solvent for determination of molecular weights. For whose kind(s) of solute would camphor...

What is the DERIVATIVE of: ln x^2 * ln 6 -(product rule)

Find the DERIVATIVE: h(x)= e^3x+2/e^3x-2 (quotient rule)

DERIVATIVE of: g(x) = Sq.root of x^4-8x^3+9 thanks

Derivative of: h(x) = e^3x+2/e^3x-2 thanks

calculate the volume of hydrogen produced when 6g of magnesium is reacted with 100cm of 1 mol l-1 hydrochloric acid no of moles of Mg= mass/gfm = 6/24.3 = 0.247 moles 1/2 mole of Mg= 1/2 mole of H2 = 0.247 moles x 100 = 24.7cm3 ???

Thank you that was really helpful Dr Bob
