Best answer
`because 1000mL HCI ` के विलियन में 0 .7 मोल HCI है
` " " therefore mL HCI ` के विलियन में ` (0.7xx 30)/(1000) ` मोल HCI है,
` " " =0.021` मोल HCI
अब समीकरण से-
` " "CaCO_3 + 2HCI to CaCI_2 +H_2O +CO_2`
` " " 1("mol") " "2("mol") `
` " "= 100g `
` because 2` मोल HCI के लिए 100 g ` CaCO_3` चाहिए
` therefore 0.021` मोल HCI के लिए ` (100xx0.021)/(2) g CaCO_3 ` चाहिए
` " " =1.05g CaCO_3`
