<u>Answer:</u>
<em>The molarity of the 
solution is 
</em>
<em></em>
<u>Explanation:</u>
The Balanced chemical equation is
Mole ratio of : KCl is 1 : 1
So moles = moles KCl
So Molarity
= 0.000402M or mol/L is the Answer
(Or) is the Answer
Answer:
The volume is 59, 3 liters. See the explanation below, please
Explanation:
STP conditions (standard) correspond to 273K of temperature and 1 atm of pressure. These values are used and the volume is calculated, according to the formula:
PV = nRT
1 atm x V= 2, 65 moles x 0, 082 l atm/K mol x 272 K
V= 2, 65 moles x 0, 082 l atm/K mol x 272 K/1 atm = 59, 3 liters
Answer:
Mass and gravitational for e is not relart
