Answer:
18.2 M
Explanation:
M(NaHCO3) = 23 + 1+ 12+ 3*16 = 84 g/mol
3.05 g * 1 mol/84 g = (3.05/84) mol NaHCO3
2NaHCO3 + H2SO4 ---> Na2SO4 + 2H2O + 2CO2
from reaction 2 mol 1 mol
given (3.05/84) mol x mol
x = (3.05/84) *1/2 = (3.05/84) /2 mol H2SO4
(3.05/84) /2 mol H2SO4 - 0.001 L
x mol - 1 L
x = [(3.05/84) *1/2]/0.001 = 18 2 mol/L = 18.2 M H2SO4
