Explanation:
The answer is the: Kalvin Scale.
The mass of the photo frame : = 549.12 g
<h3>Further explanation</h3>
Given
a photo frame
two 5.2 mm sheets = 0.52 cm
22 cm by 20 cm dimension
Required
the mass
Solution
The volume of one sheet = l x w x h
= 22 cm x 20 cm x 0.52 cm
= 228.8 cm³
Mass of one sheet :
= density x volume
= 1.2 g/cm³ x 228.8 cm³
= 274.56 g
So for two sheets of polycarbonate :
= 2 x 274.56 g
= 549.12 g
The SI unit for amount of substance is the mole. It has the unit symbol mol. <span>The mole is defined as the amount of substance that contains an equal number of elementary entities as there are atoms in 12g of the </span>isotope carbon-12<span>.</span>
