same as moles of CaCO3
CaCO3 = 100 g/mol = 40 + 12 + 48
so we have 0.25 mols of lime and will get 0.25 mols of CaCl2
Calculate the number of moles of calcium chloride Cacl2 that can be obtained from 25g of limestone CaCo3 in the presence of excess hydrogen chloride

0.25 moles of cacl2 as:
CaCo3+ HCl = CaCl2 + H2CO3
SO 1 mol of CaCO3 will give 1 mol of CaCl2.
mass of CaCO3= 25g
Molar mass of CaCO3= 100g
therefore moles of CaCO3 = 25/100 =0.25
thus 0.25 moles of CaCl2 will be produced
CaCo3+ HCl = CaCl2 + H2CO3
SO 1 mol of CaCO3 will give 1 mol of CaCl2.
mass of CaCO3= 25g
Molar mass of CaCO3= 100g
therefore moles of CaCO3 = 25/100 =0.25
thus 0.25 moles of CaCl2 will be produced
Calculate the number of moles of calcium chloride (Cacl2) that can be obtained from 25g of limestone (Caco3) in the presence of excess hydrogen chloride (HCl)
I don't know how to
yes
I don't understand

Calculate the number of moles of calcium chloride CaCl2 that can be obtained from the 20g linestone CaC3 in the presence of excess hydrogen chloride (Can=40,it=1,C=12 O = 16 ,Cl=35.5)
Mass of caco3
I don't know how to get it
oyes i know how
I don't understand how to solve it
I don't understand how to solve it
Caco3 +2Hcl(aq)=cacl2+h2o (l)+co2(g)
I didn't get the answer

I really don't know how to solve this question
Don't understand
How is that 48 gotten
