Answer:
0.108mol of Hydrogen
Explanation:
The formula for the compound is: CH3COOH
From the formula of the compound,
There are 2moles of oxygen and 4moles of Hydrogen.
If for every 2moles of oxygen, 4moles of Hydrogen is present.
Then, for 0.054 moles of oxygen = (0.054 x 4)/2 = 0.108mol of Hydrogen is present
C) powdered sugar in hot water because the sugar is already broken so it would be more faster than sugar cube in hot water
Molality = moles Pb(NO3)2/ Kg H2O
373.5 g Pb(NO3)2 X (1 mole/ 331.2 grams)= 1.13 moles Pb(NO3)2
2.00 x 10^3 g (1 Kg/ 1000g)= 2 Kg
Molality= 1.13 moles/ 2 Kg= 0.565 molal.
The right answer is Balanced
