Question

How many grams are in 0.040 moles zirconium (Zr)?

Answer 1

3.64896 grams Zr

Step-by-step explanation:

Given: amount of moles of Zr: 0.040

Find: the amount of grams of Zr

1. Find molar mass of Zr

- after looking at the periodic table, you can tell it's 91.224 g/mol

2. Solve

(
`(0.040 mol Zr)/(1)`)(
`(91.224 g Zr)/(1 mol Zr)`)

- the mol units get cancelled out, and you're left with 0.040 x 91.224 g

3. Multiply that out: 3.64896 grams of zirconium

Answer 2

91.224 gram
