Answer:
The mass of one mole of water molecule = 18 ×N
A amu
Explanation: The mass of one mole of water molecule = Mass of one molecule ×N A Also mass of one mole of water is its molar mass in grams. So the mass of one mole of water is 18 g
It becomes charged and is called an ion. Gaining an electron gives it a negative charge.
A homogeneous mixture is a mixture whose parts are the same throughout.
Answer:
Option D. 1092K
Explanation:
T1 = 273K
V1 = V
P1 = P
V2 = 2V( i.e double of original volume)
P2 = 2P (i.e double of original pressure)
T2 =?
P1V1/T1 = P2V2/T2
PV/273 = 2P x 2V / T2
Cross multiply to express in linear form
PV x T2 = 273 x 2P x 2V
Divide both side by PV
T2 = (273 x 2P x 2V) / PV
T2 = 273 x 2 x 2
T2 = 1092K
