torisob [31]3 years ago
5 0

1 mol of Silicon = 28.0855 g (in average)

then

1 mol = 6.022*10^23 atoms

then

28.0855/(6.022*10^23) g/atom

4.66381*10^-23 g per atom

If the ph of a solution is 6.1 what is the concentration of h+ ions in the solution
Drupady [299]

Answer:

10^{-6}   \frac{mol}{L}

Explanation:

Comparing to the solution consisting a pH of 5 containing 10^{-5}  \frac{mol}{L} of hydrogen ions, a solution having a pH of 6 consists of 10^{-6}  \frac{mol}{L} of hydrogen ions. A solution having a pH of 7 too will have a pH of 10^{-7}  \frac{mol}{L}.

What is the correct name for Au3N?
Reptile [31]

Answer:

option D= Gold (I) nitride

Explanation:

The name of the given compound is gold(I) nitride.

Molar mass can be determine by following way:

molar mass Au3N = (molar mass of gold × 3) + (molar mass of nitrogen)

molar mass Au3N = (196.97 × 3 ) + ( 14 )

molar mass of Au3N =  590.91 g/mol + 14 g/mol

molar mass of Au3N = 604.91 g/mol

The nitrogen has valency of -3 so three Au(+1) will require while the valency of Au is (1+) one nitrogen will require to make the compound overall neutral.

Au3N

3(1+) + (-3) = 0

+3 - 3 = 0

0 = 0

The overall charge is 0, the compound will be neutral.
