Explanation:
Incomplete Parameters provided. The density of This solution is need to solve this question.
steps to take
Find the Mass of Na2CO3 added
Mass=Mole x Molar mass
=0.05x106
=5.3g.
Find the mass of Water added
Knowing that density of Water is 1g/ml
1g/ml x 1000ml/1L x 0.4L
= 400g of Water
Total Mass = 400 + 5.3 = 405.3g
Recall
Density=Mass/Volume
Volume = Mass/density
The density of the solution isnt given
Get that
Input it into the expression above
and get the volume of solution
Molarity = Moles of solute /Volume of solution in L
THAT WOULD GIVE YOUR ANSWER
HAVE A GREAT DAY!!!
Since this is Argon it would be a noble gas
Answer:
Explanation:
molarity is moles of solute/L solution
5.5 g 1 moles Kl 1000 mL
_____ * __________ * ________ = 0.22088 M
150 ml of solution 166 grams 1 L
(39 grams K+ 127 grams I) ^
