Hello There!
When the ice melts, the water level will drop slightly but not much.
REMEMBER Ice expands so when ice melts, it shrinks back to the state of being liquid.
Cold you please repost the question
THIS IS A QUESTION REGARDING
ideal gas equation
which states that
PV = nRT
where;
P : Pressure (atm)
V : Volume (litres)
n : Number of moles of that gas(mol)
R : Real gas constant = 0.0821
T : Temperature of that gas(Kelvin)
hope this helps
Answer:
276g of Br are present
Explanation:
To solve this question we need to find the moles of CaBr2 using its molar mass -CaBr2: 199.89g/mol-. As 1 mole of CaBr2 contains 2 moles of Br we can find the moles of Br and its mass:
<em>Moles CaBr2:</em>
345g * (1mol/199.89g) = 1.7259 moles CaBr2
<em>Moles Br:</em>
1.7259 moles CaBr2 * (2mol Br / 1mol CaBr2) = 3.4519 moles Br
<em>Mass Br -Molar mass: 79.904g/mol-</em>
3.4519 moles Br * (79.904g/mol) = 276g of Br are present
