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

How will temperature affect the spontaneity of a reaction with positive H and S?
BartSMP [9]

Answer:

D.A high temperature will make it spontaneous.

Explanation:

we know that

Δ G = Δ H - TΔS

For spontaneous reaction

Δ G should be negative . If Δ G = 0

Δ H =  TΔS

T =   Δ H / Δ S

At temperature above this T , Δ G becomes negative if Δ S and ΔH are  positive .

So at a  high temperature will make it spontaneous.
