Stearic acid formula is CH₃(CH₂)₁₆COOH
The molecular mass of stearic acid is 284.48 g/mol
The mass of stearic acid in 1 ml of solution is 0.1 g
Therefore number of moles in 1 ml is - 0.1 g / 284.48 g/mol = 0.000352 mol
Molarity is number of moles in 1 L of solution
If 1 ml contains - 0.000352 mol
Then 1 L solution contains - 0.000352 /1 x 1000 = 0.352 mol/L
Therefore molarity is 0.352 M
The given equation is is
this is not balanced
The balanced equation will be:
Now as per it if we are using eight moles of HNO3 we are getting two moles of NO
so for each mole of NO we have to take four moles of HNO3
Hence the mole ratio of NO produced to HNO3 reacted will be = 1:4
Answer: 233 L of 
will be produced from 150 grams of 
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of produce = 8 moles of
Thus 2.59 moles of will produce=
of
Volume of 
Thus 233 L of will be produced from 150 grams of

V=25ml=0,025l ( you need the volume to be in l)
c = n/V
n=c*V

Answer:
0.028578 km
Explanation:
The following data were obtained from the question:
Length of whale (in mm) = 28578 mm
Length of whale (in km) =?
We can convert 28578 mm to km by doing the following:
Recall:
1 mm = 1×10¯⁶ Km
Therefore,
28578 mm = 28578 mm × 1×10¯⁶ Km / 1 mm
28578 mm = 0.028578 km
Thus, 28578 mm is equivalent to 0.028578 km
The length of whale (in km) = 0.028578 km
