Question

17. What is the molarity of a solution in
which 211g sodium hydrogen carbonate
is dissolved in a a 10L solution ​

Answer 1

Step-by-step explanation:

The molar mass of is 106. g/mol. Divide this into the given mass, to find the number of moles:

5.0 g106.gmol=0.047 mol.

This is dissolved in 200 mL = 0.200 L. Multiply each quantity by 5 to get the molarity:

5×0.047 mol5×0.200 L=0.235 molL=0.235 M
