A solution containing 10 g per dm^(3) of urea (mol.wt. = 60 g mol^(-1) ) is isotonic with a 5% ( mass//vol.) of a non-volatile solute. The molecular mass of non-volatile solute is:

A solution containing 10 g per dm^(3) of urea (molecular mass = 60 g mol^(–1) ) is isotonic with a 5% solution of a nonvolatile solute. The molecular mass of this nonvolatile solution is:

The values of the van der Waals constants for a gas a = 4.10 dm^(6) "bar" mol^(-2) and b = 0.035 dm^(3) mol^(-1) . Calculate the values of the critical temperature and critical pressure for the gas.

How many kg of CaCo_(3) [Mol. Wt = 100g mol e^(-1)] is needed to produce 336 kg of CaO [Mol wt = 56g mol^(-1)] if % yield of the reaction given is 60%. CaCO_(3)(s) rightarrow CaO(s) + CO_(2)(g)

The temperature of 4.0 mol of an ideal gas occupying 5dm^(3) at 3.32 bar (R="0.083 bar dm"^(3)K^(-1)"mol"^(-1)) is nxx10K . The value of n is
