Answer:

Number of moles = 10.6 mol

Explanation:

Given data:

Molar mass of H = 1.008 g/mol

Molar mass of C = 12.01 g/mol

Molar mass of O = 16.00 g/mol

Mass of citric acid = 2.03 kg (2.03×1000 = 2030 g)

Number of moles of citric acid = ?

Solution:

Formula:

Number of moles = mass/molar mass

Now we will calculate the molar mass of citric acid:

C₆H₈O₇ = (12.01× 6) + (1.008×8) + (16.00×7)

C₆H₈O₇ = 72.06 + 8.064+112

C₆H₈O₇ = 192.124g/mol

Number of moles = 2030 g/ 192.124g/mol

Number of moles = 10.6 mol

What mass of oxygen reacts when 84.9 g of iron is consumed in the following reaction: Fe+O2= Fe2O3
konstantin123 [22]
First we will calculate the number of moles of Iron:
n =  \frac{m}{M}
, where n is the number of moles, m is the mass of iron in the reaction and M is the Atomic weight.
n= \frac{84.9}{55.845} = 1,52 moles of Iron.
The same number of moles of Oxygen will take part in the reaction.
So 1,52= \frac{mOxygen}{32} where 32 is the Atomical Weight of Oxygen (16 x 2).
=>mOxygen=32*1,52=48,64g
