Question

caco3+2hcl=cacl2+co2+h2o of molecular mass​

Answer 1

Answer:

Explanation:

Using morality, Number of moles are calculated for 1000ml or 1L of the solution.

1000ml contains 0.75MHCl

HCl=0.75 mole.

Therefore, 25ml of 0.75M HCl will contains HCl=  

1000

0.75×25

​  

=0.01875mole

2 moles of HCl reacts with =1mole of CaCO  

3

​  

 

Therefore,

0.01875 mole of HCl will react with =  

2

1×0.01875

​  

 

=0.009375mole

Molar mass of CaCO  

3

​  

=100g

Hence, the mass of 0.009375 of CaCO  

3

​  

=no.ofmoles×molarmass=0.9375
