Answer:
0.0761.
0.0059.
Explanation:
Hello!
In this case, since the writing of numbers in standard notation given the scientific notation requires adding zeros to the left of the first nonzero digit, for the first number, we need to add two zeros as seven is the third digit position:
0.0761.
Next, we need to add three zeros as 5 would be the fourth digit:
0.0059.
Best regards!

<h3>First we find out the freezing point:</h3>
→(-23.0)-(0.0_
→-23.0 degrees C
<h3>Calculate target Colligative Molarity:</h3>
→ -23=1.86 * Cm
→ 12.37= Cm.
→i* molality
→i= 1
→12.37= 1*m
→12.37= m
<h3>molality= moles of solute(C2H6O2)/kg of solvent water</h3>
12.37m= moles C2H6O2/ 10.0kg water
123.7= moles of C2H6O2
123.7moles C2H6O2 * 62.26g C2H6O2
<h2>= 7701.56 g of C2H6O2</h2>

It is impossible to reach absolute zero because the magnitude of work that is required to remove energy from a gas in order to attain the absolute zero is so high.
<h3>What is the absolute zero?</h3>
The absolute zero is the temperature at which the movement of all the gas molecules is theoretically believed to cease. At the absolute zero, gas molecules remain at fixed positions because according to the third law of thermodynamics, the entropy of a perfectly ordered system is zero.
It is impossible to reach absolute zero because the magnitude of work that is required to remove energy from a gas in order to attain the absolute zero is so high such that it is impractical to attain the absolute zero.
