Answer:True
Explanation:
If a substance is pure, it will have exactly the same density as that reported for that particular substance in standard literature or vary within very narrow limits. Hence we can determine the purity of a gold sample by measuring it's density.
Answer:
The volume occupied by 2.18 moles of is 48.832L
Explanation:
The volume occupied by 1 mole of is 22.4 L
The volume occupied by 1 mole of any gas is 22.4 L
The number of moles of = 2.18 moles
The volume occupied by 2.18 moles of :
Hence, the volume occupied by 2.18 moles of is 48.832L
Answer:
M = 184.1 g/mol
Explanation:
Given data:
Density = 5.95 g/L
Temperature = 100°C (100+273 = 373 K)
Pressure = 755 mmHg = (755/760 = 0.99 atm )
Molar mass of gas = ?
Formula:
d = PM/RT
Solution:
M = dRT / P
M = 5.95 g/L × 0.0821 atm.L/mol.K × 373 K/ 0.99 atm
M = 182.21atm.g/mol / 0.99 atm
M = 184.1 g/mol
