Answer 1

Answer:

Molecular mass of table salt (NaCl) = 23+35.5=58.5 Now, 1000 g of NaCl cost = Rs. 2 Therefore 58.5 g of NaCl will cost = 2/1000 x 58.5 =0.117 rupees = 12 paise (approx.) (b) Cost of sugar per mole: Molecular mass of sugar (C12H22O11)= 12x12+22x1 +11x16 = 342 Now, 1000 g of sugar cost = Rs. 6 Therefore 342 g of sugar will cost = 6/1000 x 342 = 2.052 rupees = 2.0 rupees (approx.)Read more on Sarthaks.com - https://www.sarthaks.com/64221/the-cost-table-salt-nacl-sugar-c12h22o11-and-per-respectively-calculate-their-cost-per-mole?show=64222#a64222
