The mass of 50% CaCO_3 is 200 g

Explanation:

The given equation is

CaCO_3+H_2SO_4\rightarrow CaSO_4+H_2O+CO_2

From this it is clear that 1 mole of CaCO_3 will produce 1 mole of CaSO_4

Given that mass of CaSO_4 produced = 136 g

Molar weight of CaSO_4 = 136

Thus, moles of CaSO_4 produced = Mass/Molar mass = 136/136 = 1 mole

Thus, moles of CaCO_3 utilised = 1

We know that in 1 mole there are 100 gram of CaCO_3

Thus, mass of CaCO_3 = 100

But it is given that CaCO_3 is only 50% pure

Thus, total mass of CaCO_3 = 200 g

Hope this answer is helpful.
