Question

Lead forms two compounds with O2 as indicated below for a given mass of oxygen .what is the lowest whole number ratio of lead into two compounds
compound A Pb is equals to 2.98 gram and O is equals to 0.461 gram. compound B Pbis equals to 9.89 gram and O is equals to 0.763 gram

Answer 1

Answer:

0.0144 moles

Explanation:

To determine the whole-number mass ratio of lead in the first compound, find the mole ratio between lead and oxygen atoms. First, find the number of moles of lead in the first compound. Divide the mass of the first compound by the molar mass of lead. The mass of lead in the first compound is 2.98g and the molar mass of lead is207.2 g

Compound 1 moles of lead =Mass of lead ÷Molar mass of lead

=2.98 g lead×1 mole lead ÷207.2g lead

=0.0144 moles
