Answer:
-4.29 x 10^-5, -9.3 x 10^-2, and then the least is -1.370 x 10^6
Explanation:
<h3>-9.3 x 10^-2 = -0.093</h3><h3>-4.29 x 10^-5 = -0.0000429</h3><h3>-1.370 x 10^6 = -1,370,000</h3>
Now use common sense.
-0.093 is the greatest number.
Then -429,000 is in the middle.
Lastly, -1,370,000 is the least number.
<h3>So -0.0000429 > -0.093 > -1,370,000</h3>
Why?
Because as a negative number gets bigger, the more least the number is. It is the opposite of positive numbers. For positive numbers, as a number gets bigger, the more greater the number is. That is a rule.

The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100
= 34.79 %
<span>The atomic weight of 13C should be pretty close to 13.0. (If you have the exact mass, use it in the problem.) So,
9.00 g / 13.0 g/mol = 0.692 moles
Therefore, the answer should be 0.692 moles are in 9.00 g of 13C.</span>
Answer:
0.374 L
Explanation:
Step 1: Given data
Mass of silver nitrate (solute): 15.89 g
Molarity of the solution: 0.250 M
Step 2: Calculate the moles of silver nitrate
The molar mass of silver nitrate is 169.87 g/mol.
Step 3: Calculate the volume of the solution
The molarity is equal to the moles of solute divided by the liters of solution.
Due to the significant figures rules, we keep 3 significant figures.
