How many grams of cacl2 can be produced from 50.0 grams of hcl

76.0 g

Explanation:

Step 1: Write the balanced equation

2 HCl + Ca(OH)₂ ⇒ CaCl₂ + 2 H₂O

Step 2: Calculate the moles corresponding to 50.0 g of HCl

The molar mass of HCl is 36.46 g/mol.

50.0 g × 1 mol/36.46 g = 1.37 mol

Step 3: Calculate the number of moles of CaCl₂ produced from 1.37 moles of HCl

The molar ratio of HCl to CaCl₂ is 2:1. The moles of CaCl₂ produced are 1/2 × 1.37 mol = 0.685 mol.

Step 4: Calculate the mass corresponding to 0.685 moles of CaCl₂

The molar mass of CaCl₂ is 110.98 g/mol.

0.685 mol × 110.98 g/mol = 76.0 g

the answer for sodium is 0.186

the answer for rubidium is 0.251
