Concentrated hydrochloric acid is a 38% solution of hcl in water and has a density of 1.18g/ml. How many milliliters of concentrated hydrochloric acid are needed to prepare 500ml of a 1:200 hcl solution?

My calculation
500ml x 1:200 =2.5 1:200 means 1gm/200ml
2.5 x 36.5 = 91.25
240.13/1.18 = 204ml This is my answer. I am not sure. Pls helps me .
