IIT JEE/PMT Module Test 1:Chemistry : Solutions

Normal type of MCQ with one correct option The solubility of K2SO4 in water is 16 g at 50(C. the minimum amount of water required to dissolve 4 g K2SO4 is:
10 g
25 g
50 g
75 g
Normal type of MCQ with one correct option One litre of N/2 HCI solution was heated in a beaker. When volume was reduced to 600 mL, 3.25g of HCI was given out. The new normality of solution is:
Normal type of MCQ with one correct option Molarity of H2SO4 (density 1.8g/mL) is 18M. The molality of this H2SO4 is:
Normal type of MCQ with one correct option Volume of 2MHCI required to neutralise th esolution containing 1 mole of NH4CI and 1 mole of NaOH is:
1 litre
2 litre
3 litre
1/2 litre
MCQ with more than one correct option The density of air is 0.001293 g/cm3 at STP. Identify which of following statement(s) is/are correct. (a) Vapour density is 14.48 (b) Molecular weight is 28.96. (c) Vapour density is 0.001293 g/cm3 (d) Vapour density and molecular weight cannot be determined.
A,B & D
Comprehension Normality is number of gram equivalents dissolved per litre of solution. It changes with change in temperature. In case of monobasic acid, normally and molarity are equal but incase of dibasic acid normality is twice the molarity. In neutralization and redox reactions, number of milliequivalents of reactants as well as products are always equal. On heating a litre of a N/2 HCl solution, 2.750 g HCl is lost and the volume of solution becomes 750 ml. The normality of resulting solution will be
10 ml
20 ml
5 ml
40 ml
ASSERTION(REASON A. 0.28g of N2 has equal volume as 0.44g of another gas at same conditions of temperature and pressure. R. Molecular mass of another gas is 44g mol-1.
Both A and R are true and R is correct explanation of A
Both A and R are true and R is not correct explanation of A
A is true, R is false
A is false, R is true
