1 mole of TNT has a molecular weight of
12*7+5+3*14+6*16 =227g
so 0.665 mole = 227*0.665=151g

7*12+5*1+3*14+6*16=227gr
0.665 mol TNT(227gr TNT/1 mol TNT)=150.995gr~151gr

comeon now, figure it out yourself. C=12 H=1 N=14 O=16
So, 7x12+5x1+14x3+16x6=1 mol TNT=227 g
227x0.665=150.955
significant digits=3 so,
151g
