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.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
