Question

the cost of table salt(Nacl) and table sugar (C12 H22 O11) os Rs 2per kg and 6.6 per kg respectively calculate their costs per mole.
pls answer fast.... copy Mt krna☹️☹️​

Answer 1

Answer:

1000g NaCl costs = Rs. 2

58.5 g costs = 2 / 1000 * 58.5 = Rs. 0.117 i.e. 11.7 p

Write the formula of sugar it can be sucrose, fructose or lactose if u r asking 4 sugar that we take so it is lactose

C12H22O11

1000g lactose costs = Rs. 6

342g lactose costs = 6 / 1000 * 342 = Rs. 2.052

Answer 2

Answer:

we know the molar masses of these commodities. One mole of table salt (NaCl) weights 58.44 grams while a mole of table sugar weighs 342.2965 grams. The cost per gram of table salt and sugar is ₹ 0.002 (i.e. 2/1000) and ₹ 0.006 (i.e 6/1000). Therefore, the cost per mole of each of these would be 58.44*0.002 = ₹ 0.117 (~ 12 paise) per mole of NaCl and 342.2965*0.006 = ₹ 2.053 per mole of sugar. I hope this helps :)
