Answer: -

280mg

Explanation: -

The chemical formula is C14H18N2O5

Molar mass of the compound = 12 x 14 + 1 x 18 + 14 x 2 + 16 x 5 = 294 gram

Number of nitrogen atoms present in the formula = 2

Mass of nitrogen present= 14 x 2 = 28 gram

Thus 294 gram of the compound has 28 gram.

Hence 2.95grams of the compound has (28 gram x 2.95 gram / 294 gram)

= 0.28 gram

= 280 mg

Thus 280 mg of nitrogen is present in 2.95 grams of C14H18N2O5

the average speeds of gas molecules in.cylinders A,b,c,d are 0.01 m/s, 0.005m/s ,0.1 m/s and 0.5 m/s, respectively .which cylind
Darya [45]
<span>The average speed of the gas is related to the kinetic energy of the gas.  The kinetic energy of the gas is also related to the temperature of the gas. If the average speed of the gas is closer to zero, it means that it has very low motion or kinetic energy. This can be inferred that the gas has a very low temperature. At absolute zero, the motion of all the gas molecules stops. This means that the kinetic energy of the gas is also zero. Zero kinetic energy means zero average speed.</span> <span>So, the answer is cylinder B. The average speed of the gas in cylinder B is closest to zero.</span>
