Answer:
1.3M
Explanation:
Convert from grams to moles:
molar mass of HCl = 1.01g(molar mass of H) + 35.45g(molar mass of Cl) = 36.46g HCl
1.2g HCl (1mol HCl/36.46g HCl)
= .0329 mol HCl
Molarity = mol/L (important formula for concentration)
Plug your values in:
Molarity = .0329mol/.025L
1.317M - but you used two significant figures in the question, so:
1.3M
