Lastly, Snape thinks we should try one more calculation. What is the retention factor if the distance traveled by the solvent fr

Neporo4naja [7]

Answer:

0.1 is the retention factor.

Explanation:

Distance covered by solvent , $d_s= 2.0 cm$

Distance covered by solute or ion, $d = 0.20 cm$

Retention factor $(R_f)$ is defined as ratio of distance traveled by solute to the distance traveled by solvent.

$R_f=\frac{d}{d_s}$

$R_f=\frac{0.20 cm}{2.0 cm}=0.1$

0.1 is the retention factor.

A sample with a molar mass of 34.00 g/mol is found to consist of 5.9783% Hydrogen and 94.0217% oxygen. Find it’s molecular formu

kozerog [31]

Answer:

The formula is H202 (hydrogen peroxide, known as hydrogen peroxide)

Explanation:

100%----34g

5, 9783%---X= (5, 9783%x 34g)/100% =2 g

1g---1 atom of H

2g----x= 2g x 1 atom of H/1g = 2 atom of H

100%----34g

94, 0217%---X= (94,0217%x 34g)/100% =32 g

16g---1 atom of 0

32g----x= 32g x 1 atom of 0/16g = 2 atom of 0

What is the percent composition of nitrogen in N 2 O

mash [69]

Answer:

63.6%

Explanation:

The given compound is:

N₂O;

The problem here is to find the percent composition of nitrogen in the compound.

First find the molar mass of the compound:

Molar mass of N₂O = 2(14) + 16 = 44g/mol

So;

Percentage composition of Nitrogen = $\frac{2 x 14}{44}$ x 100 = 63.6%
