What is the mass in grams of 1.75 moles of Pb(OH)2?

422.1 grams

Explanation:

First find the atomic mass of each element on your periodic table.

Pb = 207.2 amu

O = 16 amu

H = 1 amu

They are two oxygen and two hydrogen atoms. Now add the atomic mass of all the elements together

207.2 + 16(2) + 1(2) = 241.2 grams

Now multiply 241.2 with the 1.75 moles

241.2 * 1.75 = 422.1

So the final answer is 422.1 grams.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance
