So i would ask this friend to draw a number line and label 6.2 on the number line. Then i would ask her if she knew what the opposite number of 6.2 is.
Yes- The number line will always continue, its indefinite. This means it can go forward or backwards. Make sure that your friend wrote 0. You always need a starting point.

Step-by-step explanation:
if you don't eat you are gonna died➡
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
