How much Na2Co3 is produced from 11g of NaHCo3

6.88 grams of is produced from 11 grams of NaHC.

Explanation:

Balance chemical reaction for the process:

2NaHC  ⇒ + O + C

Data given:

mass of NaHC given = 11 gram

atomic mass of NaHC = 84.007 grams/mole

mass of   produced = ?

number of moles of  NaHC  will be calculated as:

number of moles =

putting the values in the equation:

number of moles =

                              = 0.13 moles

from the balanced equation it can be seen that,

2 moles of NaHC reacted to give 1 mole of

0.13 moles of NaHC will give x moles of

=

x =

   = 0.065 moles of

Atomic mass of = 105.98 grams/mole

mass = atomic mass x number of moles

mass = 0.065 x 105.98

mass = 6.88 grams

so, from 11 grams of NaH 6.88 grams of is produced.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
