(b) A student knew that calciun hydroxide could be made by adding calcium to water. The student added 0.00131 mol of calcium to a beaker containing about 100 cm of water. A reaction took place as shown by the equation below. All the calcium hydroxide formed was soluble. Ca(s) + 2H,0(1) → Ca(OH),(aq) + H2(g) (1) Calculate the mass of calcium that the student added. mass of calcium %3D (ii) Calculate the volume of hydrogen gas. in dm?, produced in this reaction at room temperature and pressure, RTP. volume of hydrogen gas = dm3 ii) The student transferred the contents of the beaker to a 250 cm3 volumetric flask and water was added to make the solution up to 250 cm. Calculate the concentration, in mol dm3, of hydroxide ions in the 250 cm solution.
