First convert grams to moles:
70.0g *(mole/98.079) = 0.7137mole
Remember that molarity is moles per liter:
0.7137mole *(1/280mL) *(1000mL/L) = 25.5M

The molarity of a solution that contains 70.0 g of H2SO4 in 280 mL of solution would be 2.54 M

Molarity

Mathematically,

Molarity = mole/volume

Mole of 70 g H2SO4 = mass/molar mass

                                  = 70/98.08

                                     = 0.71 moles

Molarity = 0.71/0.28

                       = 2.54 M
