Answer:
76.5g KCl/74.55 grams per mole Kcl = x
molality= x/.085 kg H2O
Explanation:
well remember molality is moles of solute/kilograms of solvent. So it's the moles of KCl over 85 g of h20 converted into kg. if this makes sense.
Answer:
It'll be the same as 58.44 amu. This is because of the law of conservation of mass which states that total mass of reactants is always equal to the total mass of products formed.
pls give brainliest for the answer
Answer:
1 cal = 0.004187 kJ
1,500,000 cal = 6280.5 kJ
Answer: The correct option is Current W flows at a higher rate than Current Z.
Explanation: To answer this question, we will require Ohm's law.
Ohm's Law states that the current flowing through a conductor across two points is directly proportional to the voltage difference across that two points.
Mathematically,

where, V = voltage
I = Current
R = resistance
For the given question, assuming that the resistance is constant. So, the current is directly proportional to the voltage.

Hence, as the current W is greater of all the given currents so, it will flow at a higher rate.
Therefore, the correct answer is Current W flows at a higher rate than Current Z.
