Answer:

Option (B) SnS2

Explanation:

Data obtained from the question include:

Mass of Sn = 18.5 g

Mass of S = 10 g

The empirical formula of the compound can be obtained by doing the following:

Step 1:

Divide each element by their molar mass

Sn = 18.5/ 118.7 = 0.156

S = 10/ 32.07 = 0.312

Step 2:

Divide each by the smallest number

Sn = 0.156/0.156 = 1

S = 0.312/0.156 = 2

The empirical formula is SnS2

What is the wavelength of the matter wave associated with an electron (me= 9.1 x 10-31 kg) moving with a speed of 2.5 x 107 m/s?
Novay_Z [31]
Lambda = h\ Mv
lambda = 6.624 x 10^-34 / 9.1 x 10^-31 x 2.5 x 10^7
lambda = 2.9 x 10^-11 is your wavelength
