Molar mass of molecule x= 2 gr
Molar mass of molecule y= 32 gr
Molar mass of molecule `x_2y`=18 gr
Predict x and y.

Choose the wrong statement. 1. 1 mole means 6.023 xx 10^(23) particles 2. Molar mass is mass of one molecule 3. Molar mass is mass of one mole of substance 4. Molar mass is molecular mass expressed in grams

Calculate the molar mass of CO_2 .

Calculate the molar mass of Sulphur molecule , S_(i)

Calculate the mass of urea ("NH"_(2)"CONH"_(2)) required in making 2.5 kg of 0.25 molar aqueous solution. We know that molarity (m) =("Moles of solute")/("Mass of solvent in kg") and moles of soute =("Mass of solute")/("Molar mass of solute") So, find the molar mass of solute by adding atomic masses of different element present in it and mass by using the formula, Molality =("Mass of solute/molar mass of solute")/("Mass of solvent in kg")
