How many grams of h2 would be formed if 34 grams of carbon reacted with an unlimited amount of h2o? the reaction is:

c + h2o → co + h2

the atomic mass of c is 12.01 g/mole. the atomic mass of h2 is 2.016 g/mole. finish the problem by choosing the correct format for dimensional analysis.

Answer : The mass of will be, 5.66 grams

Explanation : Given,

Mass of C = 34 g

Molar mass of C = 12 g/mole

Molar mass of = 2 g/mole

First we have to calculate the moles of carbon.

Now we have to calculate the moles of .

The given balanced chemical reaction is,

From the balanced reaction, we conclude that

As, 1 mole of C react to give 1 mole of

So, 2.83 mole of C react to give 2.83 mole of

Now we have to calculate the mass of .

Therefore, the mass of will be, 5.66 grams

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
