D
Explanation:
Identifying unique features of evidence
Answer is: mass of ammonia is 14.76 grams and amount is 0.87 moles.<span>
V(NH</span>₃<span>) = 18 L.
T = 30°C = 303.15 K.
p = 912 mmHg ÷ 760 mmHg/atm= 1.2 atm.
R = 0.08206 L·atm/mol·K.
Ideal gas law: p·V = n·R·T.
n</span> = p·V / R·T.
n(NH₃) = 1.2 atm ·18 L / 0.08206 L·atm/mol·K · 303.15 K.
n(NH₃) = 0.87 mol.
m(NH₃) = n(NH₃) · M(NH₃).
m(NH₃) = 0.87 mol · 17 g/mol.
m(NH₃) = 14.76 g.<span>

Answer:
6 oxygen atoms
Explanation:
For example – glucose (C6H12O6), a common sugar molecule, is made up of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
Answer:
Explanation:
=> Weight is an attractive force which is exerted on any body.
=> It changes when the object's place changes as it depends upon the acceleration due to gravity ( g = 9.8 m/s ) which changes as we move from place to place.

Answer:
C = 75%
Explanation:
Theoretical yield = 8.17g
Actual yield = 6.13g
To calculate the percentage yield of a compound in a reaction, we'll use the formula to calculate it
Percentage yield = (actual yield / theoretical yield) * 100
% yield = (6.13/8.17) * 100
Percentage yield = 0.7503 * 100
Percentage yield = 75.03%
