The molecular weight of NaCl is 58.44 g/mol.
0.575 mol * 58.44 g/mol = 33.6 grams of NaCl
Answer:
0.0970 M
Explanation:
Remember this equation:
mol/M x V
Convert it so that you can get M.
M=mol/V
Convert the 2.14 grams of H2SO4 into mols
=0.0218
Convert mL to L
225/1000
=0.225
Plug it in.
0.0218/0.225
=0.0970 M
