Ответ:
n = 0.21 moles
Explanation:
Given that,
Volume, V = 0.84 L
Pressure, P = 4.6 atm
T = 222 K
We need to find the number of moles of Neon gas. We know that,
PV = nRT
Where
n is the number of moles
R i the gas constant, R = 0.08206 L-atm/mol-K
Put all the values,
So, there are 0.21 moles of Neon gas.
Ответ:
Molar Mass of 1 molecule of methane(CH4) = 12 + 4 = 16g/mol
That is, 16g if CH4 contain 1 mole molecule of it
= 6.022×10²³ molecules of CH4 which consists of 1 mole of C atoms and 4 moles of H atoms.
= 4 g of CH4 contains 1/4 × 6.022×10²³ molecules
= 1.5055×10²³ molecules of CH4
= 1.5055×10²³ C atoms and 6.022×10²³ H atoms
