That refers to the the amount of Lead Oxide (PbO) in the crystal. Pb is the symbol for Lead and O for Oxygen. 24% is the typical amount in most leaded crystalware.
this is in order from samllest to biggest : Bit = 1bit Byte = 8bits Kilobyte (kB) = 1024 bytes or 10^3 Megabyte (MB) = 1048576 bytes or 10^6 Gigabyte (GB) = 1073741824 bytes or 10^9 Terabyte (TB) = 1099511627776 bytes or 10^12 Petabyte (PB) = 10^15 bytes Exabyte (EB) = 10^18 bytes Zettabyte (ZB) = 10^21 bytes yottabyte (YB) = 10^24 bytes (this is as far as i know)

2.3456 grams lead (1 mole Pb/207.2 grams) = 0.01132 moles of lead =================
{(Pb-47)FIO2} - (PaCO2 X 1.25) "only use the 1.25 if FIO2 is >60%"
1 mol Pb = 207.2 grams 12.4 mol Pb = ? grams (cross multiplication) mass of (12.4 mol Pb) = (207.2 gr *12.4 mol) / (1mol) = 2569.28 g
Cellery and PB PB & Jelly Chocolate and PB
In the Penetrant PB B'laster, the PB stands for Penetrating B'laster.
because if you were to write PB then it would be a compound not a single element while Pb is lead.
Pb is a compound.
Pb , derived from Plumbum.
Pb = Lead ZN = Zinc
That is equal to 0.65 (mol Pb) * 207.2 (g/mol Pb) = 135 grams Pb 207.2 = molar mass of Pb, lead.
The chemical symbol Pb stands for "lead", Plum bum.
