26.	Consider the following statements with reference to the 'Beads and Ornaments' in the Indus Valley Civilization:1. Necklaces, fillets, armlets and finger-rings were worn by only females of Indus valley civilization.2. The practice of burying dead with ornaments was not present. 3. The bead industry seems to have been well developed at Chanhudaro and Lothal.Which of the statements given above is/are correct?1. 1 and 2 only2. 3 only3. 2 and 3 only4. 1, 2 and 3
Answer» Correct Answer - Option 2 : 3 only The correct answer is 3 only. The Harappan men and women decorated themselves with a large variety of ornaments produced from every conceivable material ranging from precious metals and gemstones to bone and baked clay. While necklaces, fillets, armlets and finger-rings were commonly worn by both sexes, women wore girdles, earrings and anklets. Hence, Statement 1 is NOT correct. Hoards of jewellery found at Mohenjodaro and Lothal include necklaces of gold and semi-precious stones, copper bracelets and beads, gold earrings and head ornaments, faience pendants and buttons, and beads of steatite and gemstones. All ornaments were well crafted. It may be noted that a cemetery has been found at Farmana in Haryana where dead bodies were buried with ornaments. Hence, Statement 2 is NOT correct. The bead industry seems to have been well developed as evident from the factories discovered at Chanhudaro and Lothal. Hence, Statement 3 is correct. Beads were made of cornelian, amethyst, jasper, crystal, quartz, steatite, turquoise, lapis lazuli, etc. Metals like copper, bronze and gold, and shell, faience and terracotta or burnt clay were also used for manufacturing beads. The beads are in varying shapes—disc-shaped, cylindrical, spherical, barrel-shaped, and segmented. Some beads were made of two or more stones cemented together, some of stone with gold covers. From archaeological finds, it appears that the people of the Indus Valley were conscious of fashion. Different hairstyles were in vogue and growing a beard was popular among all. Cinnabar was used as a cosmetic and facepaint, lipstick and collyrium (eyeliner) were also known to them.

41.	Calculate mol fraction of each component of 400 ml 4mNaOH solution. If the density of solution is 1.25 gram/ml?
Answer» Given, Volume of solution = 400 mL Molarity of NaOH = 4M Density of solution = 1.25 g/ml. Mass of solution = 400 x 1.25 = 500 g Number of moles of NaOH = 0.400 x 4 = 1.6 moles Weight of NaOH = 1.6 x 40 = 64 g ∴ Weight of water = 500 - 64 = 436 g Number of moles of water = \(\frac{436}{18} = 24.2\) ∴ Mole fraction of NaOH = \(\frac{1.6}{24.2 + 1.6} = 0.062\) ∴ Mole fraction of water = 1 - 0.062 = 0.94

41.

Calculate mol fraction of each component of 400 ml 4mNaOH solution. If the density of solution is 1.25 gram/ml?

Answer»

Given,

Volume of solution = 400 mL

Molarity of NaOH = 4M

Density of solution = 1.25 g/ml.

Mass of solution = 400 x 1.25 = 500 g

Number of moles of NaOH = 0.400 x 4 = 1.6 moles

Weight of NaOH = 1.6 x 40 = 64 g

∴ Weight of water = 500 - 64 = 436 g

Number of moles of water = \(\frac{436}{18} = 24.2\)

∴ Mole fraction of NaOH = \(\frac{1.6}{24.2 + 1.6} = 0.062\)

∴ Mole fraction of water = 1 - 0.062 = 0.94
