This will depend upon the ratio of C12 and C13, and the moles of ethoxylation. For sodium C12-13 pareth-2 sulfate (2 moles EO), equivalent weight will be approximately 400. Sodium laureth-2 sulfate with about 2 moles EO (itself a mixture of C12, C14, C16, sometimes with some C10) comes in at about 385-387. For desired properties in personal care products, 2 moles is most common.
