Explanation:
Answer: C₃H₈
Explanation:
From PV = nRT
Moles of CO2 = PV / RT =(1 x 1.037)/(0.08206 x ( 273+98.3)) = 0.0340 moles of CO2
CxHy + (x + (y/2))O₂ ----> xCO₂ + yH₂O
there is 1 mole of C in each mole of CO2 so moles of C in CO₂ = 0.0340 moles
mass of C in CO₂ = 0.0340 x 12 = 0.41 g
This means mass of C in the hydrocarbon = 0.41g
so mass of H in the hydrocarbon = 0.50 - 0.41= 0.09 g
moles of H in the hydrocarbon = mass/molar mass = 0.09/1 = 0.09 moles
molar ratio of C:H = 0.034 : 0.09 = 1 :2.67
or 3 :8
empirical formula is C3H8
Answer:
In a transverse wave the higher the wave the higher the amplitude.
Explanation:
transverse waves can be defined as:
In case of transverse waves, the vibratory motion of
particles of the medium is perpendicular to the
direction of propagation of waves.
Waves on the surface of water and light waves are examples
of transverse waves.
you are given the number of moles, from the given formula you can get the molar mass which is 12.00g/mol + 16 g/mol =28 g/mol. using the formula n=m/Mr rearrange the formula and make m subject, you thn have m=nMr therefore 7.60x 1021 mol x 28g/mol= m
m = 217268.8 g, you will notice that mol cancel out each other leaving you with g.
now convert g to litres
1 litre is equal to 1000 grams therefore
217268.8g x 1l/1000g = 217,269 litres
