15.

Moles of O2 formed = Moles of Magnesium nitrate / 2 =

RFM of O2 = 2 x 16 =

Mass of O2 = moles x RFM = 0.225 x 32 = g

Rate of reaction.

Note that this graph is a bit artificial (we would expect a curve rather than a straight line at the start of the reaction so a tangent would have to be drawn)
