How many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?

1 answer:

4 0

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3

Which is a nonpolar molecule?

Colt1911 [192]

The answer is C- sulfur hexachlorine (SF6)

SF6 is the only molecule here that is non-polar. That's due to having the fluorine atoms arranged in a way that, in pairs, they lie opposite to each other. Also, these pairs are perpendicular to each other on three different axis.

What is the empirical formula for a compound if a sample contains 3.72 g of P and 21.28 g of Cl?

Ainat [17]

Given 3.72 g of P and 21.28g of Cl, converting these to moles: ( 3.72 g P)(mol P/30.97 g P) = 0.12 mol P (21.28 g Cl)(mol Cl/35.45 g Cl) = 0.60 mol Cl P:Cl = 0.12/0.60, therefore P: Cl =1/5 Therefore, PCl5 hope it helps
