What is the mass in grams of 7.5 x 10^15 atoms of nickel?

The mass of nickel atoms is grams

Explanation:

We want to know how many grams nickel atoms equals and we know that one mole of any substance equals 6.021023 atoms

To know how many moles correspond nickel atoms apply a simple rule of three

The constant that relates the mass (grams) and the amount of substance (mol) is the molecular mass of the element The nickel molar mass is 58.69g/mol

to know how many grams of nickel correspond mol we apply a rule of three simple

The mass of nickel atoms is grams
