how many mmol are in 10 mL of water

Answer 1

1 ml of water has mass 1 g, so 10 m has mass 10g

Water having chemical formula H2O.

1 mole of H has mass 1.00784 g

1 mole of O has mass 15,999 g

So 1 mole of H2O has mass 2 x 1.00784 + 1 x 15.999 = 18.01468g

So 10g of water is (10 / 18.01468) moles

1 mmol = 1/1000 mol

so mmol is (10/18.01468) x 1000 = 555.1 mmol

So 10 ml
