Question

Which of the following has more number of molecules: 1 g of hydrogen (H2)or 1 g of methane (CH4)? (Atomic mass of H = 1 u, C = 12 u) b) Calculate the number of molecules of phosphorus (P4) present in 248 g ofsolid phosphorus. (Atomic mass of phosphorus = 31 u and NA = 6.022 x 1023 molecules)​

Answer 1

Thanks for your question...

Your required answer :

1)

• Hydrogen molecules in 1 g- 1.50575 x 10²³
• Which is higher from methane.

2)

• $Phosphorus = \frac{248}{31} = 8 \: moles$
• 1 mole of phosphorus = 6.022x1023 molecules
• = 48.176 x 1023 molecules

Answer 2

1)

Hydrogen molecules in 1 g- 1.50575 x 10²³

Which is higher from methane.

2)

Phosphorus = $\frac{248}{31} = 8 \:$ molesPhosphorus=

31

248

=8moles

1 mole of phosphorus = 6.022x1023 molecules

= 48.176 x 1023 molecules
