How many grams are there in 2 moles of sulfuric acid?

This means that one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol . This means that every mole of sulfuric acid has a mass of 98.0795 g .

How many moles of lead chloride are formed?

Complete Step-by-Step Answer:

And one mole of PbO corresponds to the formation of one mole of lead (II) chloride. Hence, by this ratio, 0.029 moles of PbO can form 0.029 moles of lead (II) chloride.

Why does lead form 2+ and 4+ ions?

The inert pair effect in the formation of ionic bonds

If the elements in Group 4 form 2+ ions, they lose their p electrons, leaving the s2 pair unused. For example, to form a lead(II) ion, lead loses its two 6p electrons, but the 6s electrons are left unchanged, an “inert pair”.

What group is lead?
