Question

How many moles are in 6.97g of Chromium?

Answer 1

0.134 moles

Step-by-step explanation:

In order to solve this, we need to find the molar mass of Chromium, which we can see from the periodic table: it is 51.996 g/mol.

Now, we need to set up an equation to convert grams to moles:

`6.97 grams*(1mol)/(51.996grams) =0.134mol`

Thus, the answer is 0.134 moles of Chromium.

Answer 2

Step-by-step explanation:

Step 1: Find how many moles

Formula →
`grams*(1 mol)/(51.996grams)`

`6.97 g *(1 mol)/(51.996g)` ← The g's cancel and there is only moles left on top

`0.13405... mol`

Answer: Rounded - 0.13405 moles of Chromium
