Chapter 3: Q3.3 CYL (page 136)

Beryllium is a light material used to fabricate transparent x rays windows for medical imaging instruments. How many moles of Beryllium are in a thin foil window weighing 3.24g?

Short Answer

Expert verified

0.360mol of beryllium are present in a thin foil window

Step by step solution

01

Step 1-Given data

Weight of foil = 3.24g

The molecular weight of beryllium is 9.0

02

Step 2- Calculating moles

Moles = given mass / molecular mass

= 3.24g/9g

= 0.360g

Therefore, 0.360mol of beryllium are present in a thin foil window
