Molarity of a solution if 124.86 g of rbf are dissolved into a solution of water that has a final volume of 2.00L is 0.59.
<h3>What is molarity?</h3>
Molarity is used for dilute aqueous solutions held at a constant temperature. In general, the difference between molarity and molality for aqueous solutions near room temperature is very small and it won't really matter whether you use a molar or molal concentration.
MOLARITY = no of moles of solute/volume of soln in litres
No of moles of rbf = 124.6/104.46
= 1.19
Volume of soln = 2
Molarity=1.19/2 = 0.59

Explanation:</h3>
Speed refers to the rate of change in distance traveled by a body in motion.
It is the ratio of distance to time taken.
It is calculated by;
Speed = Distance ÷time taken
Therefore;
Distance = Speed × time
In this case;
Time taken = 12 minutes ( but 1 hr = 60 mins)
Thus, t = 0.2 hours
Speed = 50.0 miles/hour
Thus;
Distance = 50.0 miles/hr × 0.2 hours
= 10 miles
But, we are require to give the distance in inches;
1 mile = 63360 Inches
Therefore;
10 miles = 10 × 63360 Inches
= 633,600 Inches
A. Chlorine is the most electronegative element out of the possible choices. Generally (though not 100% of the time) electronegativity increases as you go further left and up the periodic table.
The answer is letter A definitively .
I literally hate chem but I think it’s ionic, I’m not not completely sure but it kinda sounds about right . Not the best anwser haha hope it kinda helps lol
