How to calculate relative molecular mass

[From: ] [author: ] [Date: 11-10-17] [Hit: ]
what is the relative molecular mass of P?-mass of Ni = .079g = .079 / 58.7 = 0.4 of these are in each mole of P so moles of P = 0.......
One molecule of compound P contains four nickel atoms.If 1.00g of P contain 0.079g of nickel,what is the relative molecular mass of P?

-
mass of Ni = .079g = .079 / 58.7 = 0.001345 moles
4 of these are in each mole of P so moles of P = 0.001345 /4 = 0.0003364

these moles weigh 1g so 1 mole has mass of 1 / 0.000336457

= 2972 g/ mole ??
