Chloroform CHCl is an important solvent. It is produced by a reaction between methane and chlorine. How many g CH4 are needed to produce 50.0g CH4 +Cl3+ CH_4 + 3Cl_2 ->CHCl_3 + 3HCl}

I'm assuming the question is "How many g CH4 are required to produce 50 g CHCl3?"
I think the equation you wrote is screwed up (or that CH4+Cl3 may be a typo); anyway, here are the steps.
1. Write and balance the equation.
2. Convert 50 chloroform to mols. mols = grams/molar mass
3. Using the coefficients in the balanced equation, convert mols CHCl3 to mols CH4.
4. Then convert mols CH4 to g. g = mols x molar mass.
