Explanation / Answer

Question 5.3 a

Molar Mass of NaOH = 40 g/mol

Mass of 2.5 Mole NaOH = 2.5 mol x 40  g/mol = 100 gm

Question 5.3 b

Molar Mass of CO2 = 44 g/mol

Moles of 100g of CO2 = 100 g /44 g/mol = 2.27 mol

Quesiton 5.3 b

Volume of One mole gas = 24.4 Liter

Moles of Argon = 522 / 24.4 = 21.39 Moles of Ar gas present

Question 5.3 d

Density of Hexane = 0.66 g/ml

Mass of hexane = 25.9 ml x 0.6603 g/ml = 17.10 g

Molar mass of hexane = 86.18 g/mol

Moles of hexane = 17.10 / 86.18 = 0.1984 Moles

Question 5.4

Number of atoms in Al2(CO3)3 = 11

Number of atoms in BaSO4 = 6

Hence 1 mole of Al2(CO3)3 have higher number of total atoms
