Question

How many moles of Mg 3P 2(s) can be produced from the reaction of 1.8 mol Mg(s) with 0.42 mol P 482 6 Mg(s) +P 4(s) → 2 Mg 3P 2(s) a. 0.14 mol b. 0.020 mol c. 0.047 mol d.0.60 mol e. 0.740 mol

Answer 1

Option 'd' is correct

0.60 mole of Mg3P2 will formed

trivem 6 mg (8) + Pq (8) 2 mg 3 P2 (8) (1-8 mole) + (0.42 moso) → ? from the above reactions it is clear that When I mole of Pi neact with 6 mole of 'ng them & mode of mga P2 (B) formed. to mode of my require. I mole of Pq.. Therefore mole et my require. more of tq los mole of my required txlos mole et Pa | 1.8 mole ef ng required 0.30 mole of Ps But here. total number of mole of a is = 0.42, which is more them sequired mumber of model 10.3). Hemce only 0.3 moles of Pq will be consumed. Therefore. - T Number et moles mga pq produced =0.3x2 =0.lo
