Compare the ph of 0.1 m na2co3 and 0.1 m nahco3. select the statements that explain the difference. na2co3 is a stronger base. n

tatiyna

Na₂CO₃ is a stronger base while
Na₂CO₃ puts more OH- ion into solution
The strongest base is [H₊]= 10 - 12
The strongest acid is PH = 0.5
If an acid is added to neutral water the H₊
will increase but when an acid added to neutral water
the OH⁻ will decrease.

Molar mass of c16h19n305s

Masja [62]

Answer:

365.212

Explanation:

According to the given situation, the calculation of molar mass is shown below:-

Data provided

$c_{16}\ h_{19}\ n_3\ o_5\ S$

Molar mass = 16 × 12 + 19 × 1.008 + 3 × 14 + 5 × 16 + 32.06

= 192 + 19.152 + 42 + 80 + 32.06

Molar mass = 365.212

Therefore for determining the molar mass we simply solve the above equation.

So, the correct answer is 365.212
