A teaspoon of caffeine is <em>NOT</em> deadly as teaspoon of ricin
Answer:
the percentage composition of mass of nitrogen in NH OH is 42.86 %
Mass = 35.0 g
density = 1.036 g/cm³
volume = ?
therefore:
D = m / V
1.036 = 35.0 / V
V = 35.0 / 1.036
V = 33.784 cm³
answer D
I think it’s D. Stars and planets.
