Question

Calculate mass and number of molecules of sodium that is required to convert

TiCl4 to 88gms of Ti? (At.wt of Ti=44, At wt of Na =23)​

Answer 1

Given:

• Atomic weight of Ti = 44.
• Atomic Weight of Na = 23.

To find:

• Mass and molecules of Na required to convert TiCl4 to 88 gm of Ti.

Solution:

• TiCl₄ + 4Na ⇒ Ti + 4NaCl
• We need 88 gm of Ti i.e 2 moles. So multiplying above equation by 2.
• 2TiCl₄ + 8Na ⇒ 2Ti + 8 NaCl.
• We can observe that 8 moles of Na is required.
• Weight of 1 mole Na = 23 grams is  given.
• 8 moles of Na = 8*23 = 184gm.
• 184 grams or 8 molecules of Na are required.

Answer:

• 8 moles or 184 grams of Na is required to convert TiCl₄ to 88 gm of Ti.
