Answer 1

Given that, P_4 + 10 cl_2 rightarrow 4 PCIs formula mass of P_4 = 31 times 4 = 124 124 g of P_4 product of 4 moles of PCIs 1 g of P_4 produced = 4 moles of PCIs/124 g of P_4 29 g of P_4 produced = 4 moles of PCIs/124 g of P_4 times 29 g of P_4 = 4 times 29/124 moles PCIs 116/124 = 0.935 moles of PCIs P_4 + 10 cl_2 rightarrow 4 PCIs formula mass of 10 cl_2 = 10 times (35.5 times 2) = 710 710 g of cl_2 produced + 4 moles of PCIs 1 g of cl_2 produced = 4 moles of PCIs/710 g of cl_2 50 g of cl_2 produced = 4 moles of PCIs/710 g of cl_2 times 50 g of cl_2 50 times 4/710 moles of PCIs = 200/710 = 0.28169 moles of PCIs
