Response:
of 
can be found in 39.5 grams of .
Clarification:
Atomic weights: P= 31, F= 19,
The molar mass equals 1 atomic weight of P + 5 atomic weights of
F= 31+5 × 19
= 31+95
=126 g/mole
The number of moles in 39.5 gm of
equals 
= 
=0.3134 moles
1 mole of any substance encompasses
0.3131 moles comprises 0.3134
Thus, of can be found in 39.5 grams of .

The density of the cube is calculated as follows: 38.234 kg/m³ or 0.038234 g/mL. Explanation: We begin with the formula for volume, which is expressed as m³ where 'm' indicates the side of the cube. Given that the cube’s side is 0.65 m and its mass measures 10,500 grams, this converts to 10.5 kg (as 1000 grams = 1 kg). The volume is calculated as (0.65)³, equaling 0.274625 m³. Density is determined by dividing mass by volume, leading to a density of 10.5 kg divided by 0.274625, resulting in 38.234 kg/m³. To convert, 1 kg/m³ equals 0.001 g/mL, thus resulting in 0.038234 g/mL.
1. Stars originate within clouds of gas and dust referred to as nebulas. 2. These clouds are drawn together by gravitational forces. 3. Once sufficient heat and pressure accumulate, nuclear fusion commences, representing the birth of a star.
