The density (in $g \ mL^{-1}$) of a $3.60 \ M$ sulphuric acid solution that is $29 \% \ H_2SO_4$ (Molar mass $= 98 \ g \ mol^{-1}$) by mass will be

$A$ solution is prepared by adding $1 \ mole$ of ethyl alcohol in $9 \ mole$ of water. The mass percent of solute in the solution is. . . . . . . (Integer Answer)
(Given : Molar mass in $g \ mol^{-1}$ Ethyl alcohol : $46$,
water : $18$)

When the concentration is expressed as the number of moles of a solute per litre of solution,it is known as:

$250 \ g$ solution of $D$-glucose in water contains $10.8 \ \%$ of carbon by weight. The molality of the solution is nearest to (Given: Atomic weights are $H = 1 \ u, C = 12 \ u, O = 16 \ u$)

Which of the following solutions has the highest amount of solute (in grams)?

$A$ solution is prepared by dissolving $24.5 \ g$ of sodium hydroxide in distilled water to give $1 \ L$ solution. The molarity of $NaOH$ in the solution is (Given that molar mass of $NaOH = 40.0 \ g \ mol^{-1}$) (in $M$)
