Which of the following is the largest volume? a) 2.3 x 101 m3 b) 2.3 x 108 cm3 c) 2.0 x 104 dm3 d) 2.0 x 108 mm3

The largest volume is b) 2.3 × 10⁸ cm³.

Convert each measurement to the same units (say, cubic metres).

a) 2.3 × 10¹ m³ = 2.3 × 10¹ m³

b) 2.3 x 10⁸ cm³ × (1 m/100 cm)³ = 2.3 × 10² m³

c) 2.0 x 10⁴ dm³ × (1 m/10 dm)³ = 2.0 × 10¹ m³

d) 2.0 x 10⁸ mm³ × (1 m/1000 mm)³ = 2.0 × 10⁻¹  m³

The volume of 2.3 × 10² m³ is the largest volume.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
