<span>the si unit of temperature is its degree celsius because its online you could've just looked it up </span>

Answer:</h3>
Concentration will be 0.1 M and not 0.050M
<h3>
Explanation:</h3>
This explains why the molarity is not 0.050 M but 0.1 M
Molarity is the concentration of a solution in moles per liter.
Therefore,
Molarity = moles ÷ Volume
In this case,
We have 1.34 g of CuCl₂ and a volume of 100 mL
To get the molarity we need to find the number of moles in 1.34 CuCl₂
Number of moles = Mass÷ molar mass
Molar mass of CuCl₂ = 134.45 g/mol
Therefore,
Moles of CuCl₂ = 1.34 g ÷ 134.45 g/mol
= 0.009965 moles
= 0.01 moles
Then we can calculate the molarity;
Molarity = Number of moles ÷ Volume
Volume of the solution is 100 mL or 0.1 L
Molarity = 0.01 moles ÷ 0.1 L
= 0.1 M
Therefore, the concentration of 1.34 g CuCl₂ in a volume of 100 mL is 0.1 M and not 0.050M.
It should be 2+ because Ba is in the 2nd group which means it needs two more electrons.
Answer:
Explanation:
At STP, 1 mole of hydrogen can occupy a volume of 22.4 liters. At STP, 3 moles of hydrogen can occupy a volume of 2×22. 4=44. 8 liters
