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

Photon
L = (1⅕)W= (6/5)W
LW = 480 in²
(6/5)W² = 480
W² = 480 × ⅚ = 400
W = 20 in
L = (6/5)W =24 in
Answer:
16'1"
A) 6' + 5' + 3' = 14'
B) 10" + 4" + 11" =25" = 2'1"
A+B= 16'1"
1 Feet = 12 Inches
3 2/5 + 4 1/5
3 + 4 = 7
2/5 + 1/5 = 3/5
The answer is 7 3/5
