The volume of 6.00M HBr in milliliters that would be required to react with 2.46 g of na2co3 is 7.6mL

The balanced chemical equation is:

Na2CO3(s)1 mol+2HBr(aq)2 mol→2NaBr(aq)+H2O+CO2

Moles of Na2CO3 present =2.46/106=0.023

(Molar mass =2×23+12+3×16=106)

Now, according to the equation,

1 mol of Na2CO3 requires 2 moles of HBr

0.023 mol of Na2CO3 requires moles of HBr = 2×0.023=0.046 mol

Now, 6 mole of 6M HCl is present in 1000 mL

0.046 mol of 6M HCl would be present in =(1000/6)×0.046 =7.6 mL

What is volume?

  • Volume is a measure of the occupied three-dimensional space.
  • Often quantified numerically using SI units (such as cubic meters and liters) or using various imperial or US customary units (such as gallons, quarts, and cubic inches).
