<h3>We know that :</h3>
<h3>Asked :</h3>
A = …?
<h3>Solution :</h3>
A = ½ (a + b) × h
A = ½ (6 + 2) × 3
A = ½ (8) × 3
A = 4 × 3
A = <u>12</u> square units.
what they are saying is n is 3 so 3+11=14
Step-by-step explanation:
17/15 as a mixed number is 1 2/15. 2 31/18 as a mixed number is 54 13/18.
M(Pb(C2H5)4 = M(PB)*1 + 4*( M(C)*2 + M(H)*5)
M(Pb(C2H5)4 = 207.2 + 4(12.0*2 + 1.0*5)
M(Pb(C2H5)4 = 207.2 + 4(28.0 + 5)
M(Pb(C2H5)4 = 207.2 + 4*33
M(Pb(C2H5)4 = 207.2 + 132
M(Pb(C2H5)4 = 339.2 g/mol
