Answer:
Atomic mass of N relative to H is 13.9.
In periodic table mass of N is around 14 RAM
Explanation:
1 mol of ammonia has 1 mol of N, and 3 mole of H
NH₃
1 mol of H weighs 1 g, so the mole of H, present in ammonia are:
1.712 g / 1 g/m = 1.712 mole
Since the ratio is 1:3
1.712 mole/3 = 0.57 mole of N are present in the amonia
To calculate the atomic mass of N relative to H, let's consider it as molar weight.
Molar weight = mass / mole
7.933 g / 0.57 mole = 13.9 g/m
Cm^3 = mL
1.11 g/cm^3 = 1.11 g/mL
Density (g/mL) multiplied by volume (mL) will give us the mass (g)
1.11 g/mL * 387 mL = 429.57 g
And since we have 3 significant figures, we have 430. g.
Answer
Susan can process wind speed data from different regions.
Explanation
A Doppler radar is used in weather forecasting in measuring the direction and speed of objects such as drops of precipitation. It determines if the movement occurring in the atmosphere is horizontally towards or way from the radar. Susan can obtain velocity data about objects at a distance which might be water droplets thus be able to predict a coming weather
