Explanation:
if you have substance , it is can be SOLID or LIQUID or GAS (States of Matter )
and maybe this substance react with other substance or element and produce a new substance or dissociate to element
for EX : you have a H2O
it's may react with NaCl to produce NaOH and HCl
or the H2O dissociate to H2 and O
Good LUCK
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
